SIV864/PHM961 Special Module on Multimedia Processing and Communication

Part A: Please read the paper on JPEG here and give its those salient points which in your opinion add to the class lectures. [Note: It is not expected that one would be able to understand each and every detail of the paper. The idea is to make you read the paper.]

Part B: Implement the following parts of the transform coding/decoding.

• Convert the image to gray scale (monochromatic) image using an in-built function
• Division of image to blocks (sub images)
• Transform of blocks
• Truncation or quantization (can try different strategies).
• Inverse transform and reconstruction of image from the retained coefficents.
• Use Fourier Transform and Discrete Cosine Transform and compare and show the error enountered for the same number of coefficients retained for each.

Note:
1. This assignment is meant for reading of material related to what has been covered in the class and apply to some of the problems as above.
2. For the answers for the above problems if there is any sharing of information from your friend/internet/other reference material, it is desired that you please include/acknowledge the name of that reference.
3. You may submit the report of your assignment as a word or pdf document.
For Part B, you may do the implementation in MATLAB or any other programming environment such as C/C++/Java
