This program also provides the LDPC code with the size 4512*2256, and 1/2 code.)

This project is on type of techniques used to enhance an image, detection of edges. In this project we have used neighborhood processing for the edge detection using convolution mask. And to increase the contrast of an image, we stretched each component of an rgb image.
