SIV864 Special Module on Media Processing and Communication

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 Discrete Fourier Transform and Discrete Cosine Transform and compare and show the error enountered for the same number of coefficients retained for each.

Note:

You may do the implementation in MATLAB or any other programming environment such as C/C++/Java with appropriate library for handling images.
The submission should include the code and a report (pdf) of the analysis of results. This may be combined in one zip file.
