[SOLVED] Cmpt 365 multimedia systems project 2

Create a program that reads an uncompressed TIFF image file and compress/decompress it.
Your program should first show an open file dialog box for the user to select the TIFF file, which follows the
same format specification/constraints as in Project 1.
Your program should compress the image with your own (1) lossless compression and (2) lossy compression,
and then decompress and output the results as follows:
1. Displays the original image (right side) together with the decompressed image from lossless compression (left
side) ( – yes, these two should look exactly the same, but if you use some conversions or transforms, e.g., RGB
to YUV, then there would be small round off errors; it’s good if you provide discussions on their impact) ; also
display the compression ratio at the bottom;
2. Refreshes by the original image (right side) together with the decompressed image from lossly compression
(right) of a compression ratio around 10; also display the exact compression ratio at the bottom;
3. Refreshes by the original image (right side) together with the decompressed image from lossly compression
(right) of a compression ratio around 20; also display the exact compression ratio at the bottom.
We can accept a range of [8,12] for compression ratio 10 and [16,24] for compression ratio 20.
You should submit the source code together with its executable version. You should also submit a short report
(2-3 pages) describing the following issues:
1. The key techniques used in your solution and their respective impacts to the image quality. You may
want to draw a simple diagram for the processing flow (like that for JPEG in the slides);
2. The percentage of the computation times of the different modules (try to figure out a way to measure
them);
3. Image quality comparison with other commercial tools (e.g., Photoshop);
4. Any other problem/interesting issues you have encountered.
Grading scheme:
2 of 2
1. File input (2 marks)
2. Lossless compression implementation (4 marks)
3. Lossy compression implementation (8 marks)
4. Discussion in report (6 mark)
