Implementation of Image Compression Algorithm using MATLAB

Abstract

In current scenario, Internet becomes a handy tool to everyone and everyone wants lot things in a very compact form so-that less amount of data can be stored or captured in a very small space. As Internet is act as medium of transportation of documents (such as multimedia documents). In this paper, a compression technique is being representated to compress the on form of multimedia document such as image using MatLab. Since, image contains a lot of information in dot form and required a huge space on hard disk. The Image compression technique used discrete cosine transform to deal with the real value during the compression of an image. Using DCT in compression leads to easy calculation of image data in frequency domain.
