1. Track Ball, Paddle and Count How Many Times Ball HitsPaddle in Video Game

Your program needs to track the ball (or balls) and the paddle in each of the video game framesequences below. The program also needs to count how many times a ball hits the paddle. It is up to youif the count starts from zero or from one. Your program should produce a video where a mask (e.g., ared rectangle) is drawn around the paddle and a mask of a different color (e.g., a green rectangle) isdrawn around each ball in each frame of the video where they are present. The number of times the ballor balls hit the paddle should be visible in each frame where the paddle is present. For instance, you canput this number above the paddle.

A ZIP file with individual frame JPEG files that constitute the sequence is provided. The frame rate of eachsequence is 60 frames per second. A frame sequence should serve as input for your program. The framesequences were generated using a free video game SDL-BALL [http://sdl-ball.sourceforge.net/].

The number of frames and the duration of your video should match the number of frames and durationin the input frame sequence.

To simplify grading your submission, you may upload your videos into Youtube and embed them in thiswiki as described in this tutorial. Embedding your videos is optional.

Even if you embed the videos, you still must attach the video file into the wiki. Attaching your outputvideos is MANDATORY.

Code

You only need to solve this problem in one language. Please use the correct code block and delete theother one that you won't use. Please make sure that the code is formatted properly and the instructionsfor reproducing the output videos are provided together with the code. If you use third-party librariesother than OpenCV and MATLAB, then make sure that the code is referenced and that it is possible toobtain it to reproduce your results.

2. Track Wrist, Block, and Object during Manipulation

Your program has to track the robot or human wrist, the block (i.e., a brick or a ball that the robotgrasps first), and the object (i.e., the basket that the robot grasps second) in each manipulation videoframe sequence below. The program also needs to draw the path of the robot's wrist, the container, andthe object through the manipulation sequence. Your program should produce a video where the centerof each tracked feature is clearly indicated (e.g., using circles of different colors). The path of the trackedfeatures should through the video should be also shown. If a feature is occluded or leaves the frame,then it should not be tracked during that frame. Once the feature re-appears, its tracking should berestored.

A ZIP file with JPEG files for each frame in the sequence is provided. The robot recorded video at 15frames per second.

Please use 30 or 60 frames per second for your video with tracking to speed up play back, which willsimplify grading. It is advised to put a label in your video that gives the speedup factor (e.g., “2x” if yourvideo is generated at 30fps or “4x” if it is generated at 60fps).

To simplify grading of your submission, you may upload your videos with tracking into Youtube andembed them in this wiki as described in this tutorial. Embedding your videos is optional.

Even if you embed the videos, you still must attach the video files into the wiki. Attaching your outputvideos is MANDATORY.

3. EXTRA CREDIT: Track Mouse Cursor

Write a program to track the mouse cursor hovering over Google home page. Your program should drawa mask (e.g., a green rectangle) over the tracked location of the mouse pointer. In addition, yourprogram should also draw the path of mouse through the sequence of frames. The color model maychange abruptly through the video.

A ZIP file with JPEG file for each frame in the sequence is provided.

Please use 30 or 60 frames per second for your video with tracking to speed up play back. To simplifygrading of your submission, you may upload your videos with tracking into Youtube and embed them inthis wiki as described in this tutorial. Embedding your videos is optional.
