Green Screen Effects

1. Balance Beam

Ever wanted to walk across a small beam way high up in the air? Me neither, but you can make a cool effect that looks like you did. Throwing a green screen on the ground and then building a balance beam over top of it you can start recording the main shot. Strap a GoPro to your head and look down while walking across the beam.

2. Shrink Effect

Okay this one is really easy. Take some footage of a person walking in front of a green screen, ideally looking at something to be featured in the main shot to sell the effect. Then take a close up of a small object. Key out the green behind the person, take the footage and drop it over your close up, and then scale it to match. Duplicate it, mirror it horizontally to act as a reflection and then drop the opacity and add some blur to make it look more realistic. It’s a fun little trick.

3. Floating Object

This is a simple one, making an object appear to be floating. This is another two clip shot. First, take a shot with the object hanging in front of a blue screen. Then on the same location, take another shot but while pretending to levitate the hammer. Masking around the hammer will get rid of the string for hanging, key out the blue, and then dropping it on top of the other clip is all you need.

A green screen is a green surface used as a background when filming so that any image can replace the screen behind the actor or presenter. Shooting with a green screen involves filming a person or adding visual effects in front of a solid color. Then, by digitally removing or “keying out” that color, you can drop that scene onto the background of your choice in post-production. Removing the colored background is also referred to as “chroma keying.”

Steps with Images

The first step is to record footage in front of a green screen so that you can import it into WeVideo as a media file. To capture footage that is optimal for the Green Screen effect, please ensure the following:

There is ample lighting distributed evenly around you with no shadows.
You are in front of a solid background with no creases. Green or blue is the recommended color for your background.
The quality of your camera is high enough so that the footage is not pixelated or grainy. 720p HD footage or above is recommended.

Step 2) Add media to the Timeline

Once you’ve captured the footage you want to use for the Green Screen effect, import that media file and add it to the Timeline. Remember to place the green screen footage in the Video 2 track and the clip you would like to use as the background in the Video 1 track.

If you are using more than two video tracks, place the green screen footage in the track above whichever track holds the background footage to ensure proper layering techniques are used.

Step 3) Open the clip editor

Double click on the green screen clip in the Timeline to open the clip editor. In the clip editor, navigate to the Color Keying tab.

Step 4) Use the color picker tool

Select the color picker tool and then click anywhere on the green screen footage to apply the effect.

Step 5) _(optional) Adjust the color settings

The Green Screen effect should automatically apply without the need to adjust the color settings. However, if you would like to make these additional modifications, you can use the scroll bars to make the following adjustments:

**Show- You can select Mask to reveal a black and white representation of the mask you are applying using the color keying tool. Notice that the black area represents transparent sections of your video, while the white area represents opaque sections.
**Color Balance- This adjusts how selective the effect is. The further right you scroll, the wider the range of tints and shades are removed.
**Color Sensitivity- This smooths out any pixelation and rough edges of color that remain.
**Defringe- This helps reduce color bleeding at the edges of your mask. The left and right sliders control the level of white and black respectively to help match the edges of the mask with your new background color.

Mastering OpenCV Object Tracking: A Comprehensive Guide for Beginners and Experts

OpenCV Tracking is a popular method used for tracking objects in a video in real-time. OpenCV is a powerful library used for image processing and computer vision applications.

From real-time video analysis to Augmented Reality, OpenCV Tracking has a wide range of uses and can help both private and public sectors to detect and track the desired object in an image or video.

In this comprehensive guide, we’ll explore OpenCV Tracking and its pre-built trackers**.** We will use the OpenCV library and Python to implement this Object Tracking application.

What Is OpenCV
The Pre-Built Algorithms OpenCV Offers For Object Tracking
Implementation In Python And OpenCV

Part 1. What Is Object Tracking?

Object Tracking determines the location of an object in a video and can be used for a variety of purposes, including surveillance, security, traffic control, digital forensics, anomaly detection, gesture recognition, visual surveillance, human-computer interaction, augmented reality, and robot vision.

Even though it may seem easy for an average person, object tracking is quite complex for computers because they have to analyze a set of frames and estimate the object’s trajectory based on numbers instead of images.

Because of how complicated it is, Object Tracking is considered one of the most difficult tasks in computer vision. Even though it’s a challenge, it’s not impossible to accomplish.

And there are two levels of Object Tracking that you should learn about:

1. SOT & MOT

Single Object Tracking (SOT): SOT is a tracking algorithm that creates advanced appearance models and/or motion models to manage difficult issues like out-of-plane rotations, illumination variations, or scale changes.
Multiple Object Tracking (MOT): MOT tracks every part of a video and is mainly concerned with mid-level tasks and serves as a foundation for high-level tasks.

2. The Difference Between Tracking And Detection

After knowing what Object Tracking is, there is another concept you should also be aware of - Object Detection.

The Object Tracking and Object Detection are two important methods in computer vision. Object Tracking tracks the position of a given object in an image in real-time, while Object Detection identifies and localizes objects in an image or video. That is the difference.

Part 2. Types Of Object Tracking

Image Tracking

Image tracking allows users to interact with digital content more naturally and helps users move and interact with digital objects in the same manner as they will with real-world physical objects.

Image tracking can be used in various augmented reality (AR) applications, such as AR gaming, shopping, and navigation. Moreover, you can also use it for educational purposes, such as teaching anatomy or providing instructions for a difficult task.

Video Tracking

Video tracking is the process of tracking objects in a video sequence and can be used for various applications, such as detecting and counting objects in a scene, understanding their motions, and recognizing activities.

Part 3. What Are The Difficulties Of Object Tracking?

As what has been mentioned above, the use of object tracking is versatile. However, there are some challenges associated with Object Tracking, such as:

Background Clutter: The background can impact extracting an object’s features. If the background is more densely populated, detecting or tracking the object of interest can be more difficult.

Occlusion: This is a phenomenon where the object being tracked is affected by the background or foreground. This causes the tracking algorithm to get confused due to multiple objects coming close together, hence, losing track of the object.

Varying spatial scales: Varying spatial scales refer to the target object being of a different size or shape, which can confuse the algorithm, leading to errors.

Training and Tracking Speed: If the object is moving too fast or is too small, it can be difficult to track. Therefore, the tracking module has to be designed to track, identify, and localize objects in a matter of seconds.

Part 4. Stages Of The Object Tracking Process

After the introduction of object tracking technically, let’s learn about its mechanism of it from two sides: periods of the working process and the way it tracks.

1. Stages Of The Object Tracking Process

Following are the stages of the Object Tracking process:

Target Initialization

Target initialization is the first step in Object Tracking and involves defining the targets or objects of interest and drawing a bounding box around them in the initial frame. After that, the tracker has to detect the position of the object in the frame while drawing the bounding box.

Appearance Modeling

Appearance modeling is important for understanding how an object will look under different circumstances. If the object being tracked changes appearance due to different lighting, angle, or speed, the tracking algorithm may lose its information and the object itself. Therefore, it has to be conducted to let the algorithm detect the changes and distortion.

Motion Estimation

Motion estimation entails the capacity of the model to anticipate an object’s future position with precision.

Target Positioning

Motion estimation is a process of approximating the most likely region where an object could be present. After the object’s location is approximated, a visual model can be used to determine the target’s location more accurately.

2. Methods Of Object Tracking

Here’re some methods of Object Tracking:

OpenCV-Based Object Tracking

OpenCV Object Tracking method is widely used because it offers several built-in functions designed specifically for this purpose, such as GOTURN, MIL, MediandFlow, and CSRT. The tracker type you select will depend on your specific application design. Each tracker has its pros and cons, so there is not a single type of tracker ideal for all applications.

MDNet

Multi-Domain Convolutional Neural Network Tracker is a convolutional neural-based visual tracker and has won the VOT2015 challenge. Moreover, it is composed of domain-specific layers, branches, and multiple shared layers.

The MDNetT tracker is a deep neural network that is trained on numerous Object Tracking datasets. The tracker is designed to work in multiple domains, including video, text, and images.

DeepSort

DeepSort algorithm can track objects in real-time and uses YOLO v3 to compute the bounding boxes around the objects in a frame.

DeepSort uses Kalman filter from Simple Online and Realtime Tracking algorithm and an identification model, ReID to interlink bounding boxes and object tracks.

ROLO

ROLO is a novel Object Tracking method that uses recurrent neural networks (RNNs) to learn object-specific Spatio-temporal representations. This method works with YOLO, an object detection algorithm, and an LTSM for determining the trajectory of an object.

Part 5. The powerful backup: OpenCV

We have demonstrated how powerful OpenCV Tracking is and how it works. However, do you wonder what OpenCV is? How it supports the tracking goals being achieved? In this part, we will focus on OpenCV and help you better understand the the underlying mechanisms.

1. What Is OpenCV?

OpenCV is a powerful library that allows you to perform image processing, deep learning, machine learning, and computer vision tasks on live video feeds. Moreover, it can be used to detect objects, track their movements, and recognize faces.

It can help process the data that have videos and images and has been used in various applications, such as object recognition and detection, autonomous cars, robots, medical image analysis, automated surveillance, and anomaly detection.

2. The Pre-Built Algorithms OpenCV Offers For Object Tracking

There are 8 pre-built algorithms that OpenCV offers for Objects Tracking. All of them have their uniquility and here we will present their pros and cons for your better understadning.

Tracker	Pros	Cons
BOOSTING Tracker	Track objects accurately.	Relatively slow. Unable to stop when an object is lost.
MIL Tracker	Strong resistance to noise. Gives accurate results.	Low speed. Unable to stop tracking once the object is lost.
KCF Tracker	High speed and accuracy. Stops tracking when the object is lost.	Inability to continue tracking objects once lost.
TLD Tracker	Resistance to overlapping and object scaling.	Unstable in object detection and tracking. Constantly loses object.
MEDIANFLOW Tracker	High accuracy and speed. Accurate in determining the object’s loss.	Loses object quickly due to high speed.
GOTURN Tracker	Shows resistance to obstructions and noise.	If the speed of an object is high, it shifts to another object.
MOSSE Tracker	Able to continue tracking after the object is lost. High speed.	Loses object easily if very high speed.
CSRT Tracker	Good resistance to overlapping. High accuracy.	Low speed. Unstable when an object is lost.

3. Implementation In Python And OpenCV

Part 1. What Is Object Tracking?

Because of how complicated it is, Object Tracking is considered one of the most difficult tasks in computer vision. Even though it’s a challenge, it’s not impossible to accomplish.

And there are two levels of Object Tracking that you should learn about:

1. SOT & MOT

Single Object Tracking (SOT): SOT is a tracking algorithm that creates advanced appearance models and/or motion models to manage difficult issues like out-of-plane rotations, illumination variations, or scale changes.
Multiple Object Tracking (MOT): MOT tracks every part of a video and is mainly concerned with mid-level tasks and serves as a foundation for high-level tasks.

2. The Difference Between Tracking And Detection

After knowing what Object Tracking is, there is another concept you should also be aware of - Object Detection.

Part 2. Types Of Object Tracking

Image Tracking

Image tracking allows users to interact with digital content more naturally and helps users move and interact with digital objects in the same manner as they will with real-world physical objects.

Video Tracking

Part 3. What Are The Difficulties Of Object Tracking?

As what has been mentioned above, the use of object tracking is versatile. However, there are some challenges associated with Object Tracking, such as:

Background Clutter: The background can impact extracting an object’s features. If the background is more densely populated, detecting or tracking the object of interest can be more difficult.

Varying spatial scales: Varying spatial scales refer to the target object being of a different size or shape, which can confuse the algorithm, leading to errors.

Part 4. Stages Of The Object Tracking Process

After the introduction of object tracking technically, let’s learn about its mechanism of it from two sides: periods of the working process and the way it tracks.

1. Stages Of The Object Tracking Process

Following are the stages of the Object Tracking process:

Target Initialization

Appearance Modeling

Motion Estimation

Motion estimation entails the capacity of the model to anticipate an object’s future position with precision.

Target Positioning

2. Methods Of Object Tracking

Here’re some methods of Object Tracking:

OpenCV-Based Object Tracking

MDNet

The MDNetT tracker is a deep neural network that is trained on numerous Object Tracking datasets. The tracker is designed to work in multiple domains, including video, text, and images.

DeepSort

DeepSort algorithm can track objects in real-time and uses YOLO v3 to compute the bounding boxes around the objects in a frame.

DeepSort uses Kalman filter from Simple Online and Realtime Tracking algorithm and an identification model, ReID to interlink bounding boxes and object tracks.

ROLO

2. The Pre-Built Algorithms OpenCV Offers For Object Tracking

There are 8 pre-built algorithms that OpenCV offers for Objects Tracking. All of them have their uniquility and here we will present their pros and cons for your better understadning.

Tracker	Pros	Cons
BOOSTING Tracker	Track objects accurately.	Relatively slow. Unable to stop when an object is lost.
MIL Tracker	Strong resistance to noise. Gives accurate results.	Low speed. Unable to stop tracking once the object is lost.
KCF Tracker	High speed and accuracy. Stops tracking when the object is lost.	Inability to continue tracking objects once lost.
TLD Tracker	Resistance to overlapping and object scaling.	Unstable in object detection and tracking. Constantly loses object.
MEDIANFLOW Tracker	High accuracy and speed. Accurate in determining the object’s loss.	Loses object quickly due to high speed.
GOTURN Tracker	Shows resistance to obstructions and noise.	If the speed of an object is high, it shifts to another object.
MOSSE Tracker	Able to continue tracking after the object is lost. High speed.	Loses object easily if very high speed.
CSRT Tracker	Good resistance to overlapping. High accuracy.	Low speed. Unstable when an object is lost.

3. Implementation In Python And OpenCV

Now, after theoretical explanation of OpenCV and OpenCV Tracking, let’s learn Object Tracking OpenCV Python with coding and our simple and step-by-step instructions:

Install The Dependencies

Install the pycharm app on your PC, and launch it. Create a new project and go to Terminal. Install the opencv-contrib-python package by pasting the following command into the Terminal.

Set Up the Trackers

Now, create a Jupyter-notebook and set up the trackers with this code:

Tasks:

cv2. version returns the OpenCV library version number.
Save the name of the eight trackers.
Check the list for the version you are working on and create a tracker object based on the number.

Capture The Video Input

For capturing the video input, write the following lines of code:

Tasks:

Use the VideoCapture class to capture a video via the webcam or get a saved one from your PC.
In VideoCapture - line 2, give the path to your video.
Comment on the second line to use the webcam for tracking and uncomment the third one.

Creating The Bounding Box And Initializing The Tracker

Define an initial random bounding box or select the choices for the object you want to track with the following code:

Start The Tracker And Check The Output

Finally, write the below code lines to start the tracker:

Tasks

Read each video frame.
Start the timer and, through the tracker, determine the trajectory of the object.
Use the trajectory to draw the bounding box.
The program will start tracking. Afterward, press the space bar to stop tracking.
