Matlab code for implementing various image and video processing questions.

1a: Write a Matlab program to find all words in the provided static images and draw rectangles around them. Save each result in a separate image file.

2a: Write a Matlab program to detect the words in the selected/highlighted squares. Then overlay the image with the coordinates of those grid squares, e.g., (1,4), (2,1), (2,4) and (3,3) for the first test image. Also, print the coordinates in plain text on the console.

3a: Write a program that changes the highlight color for selected words from gray to blue before writing the result to the output video.

3b: Write a program that detects when the purple group tile appears (light blue in the second input) and then changes all pixels with this color to light brown. Save your result as a new output video file.

4a: The game gives you four chances to solve the puzzle. Write a program that detects the number of remaining chances (gray circles) and augments the video frame with a red integer that is equal to that count. Save your result to a new output video.

4b: For each video below, print/overlay with text the color of the group block for each successful choice. e.g. Blue, Yellow, Green, Purple.

5a: Write a program that detects all movement in the input video and outputs the motion history as a new video. That is, the output video must contain only the pixels that moved in the last T frames and their color must reflect how recent was their movement (bright white most recent; dark gray most distant).

5b: Write a program that tracks which selected squares moved and overlays the output video with their trajectories. That is, plot a line that tracks the center of each grid as it moves on the screen.
