Implementation of Image compression using DCT
(for learning purposes to understand RLE encoding)
Basic implementation of image compression using DCT has been done. Note that JPEG compression exploits many other techniques to achieve higher compression. Here only Quantization (lossy step) & Run length encoding has been done.
The working can be simply explained as :
The compressed image has block-artifacts which can be seen easily.
