Hello Techyv Experts,
I need to have tutorial on Unified Modeling Language. If anyone can also provide the sequence and the class diagram of data compression of an image, that will also help me. So please do the needful for helping me by providing the details on this regard.

Sequence and the class diagram of data compression
Well the compression occurs as mentioned:
1. Image Load.
2. Take sub-image of size 8×8.
3. Apply cosine transform for this sub image.
4. The above coefficients are normalized using normalized matrix and compression takes place using run length coding.
The first picture shows how classes are associated with each other for the image compression.
In second image, its shown that how message passing occurs among classes i.e.load-image, subimage, DCT_transform, quantizations, run_length_code and compress_image.
