A Study of Image Compression Methods
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2013, Vol 13, Issue 2
Abstract
Image compression is now essential for applications such as transmission and storage in data bases. In this paper we review and discuss about the image compression, need of compression, its principles, and types of compression and various algorithm of image compression. This paper attempts to give a recipe for selecting one of the popular image compression algorithms based on Wavelet, DCT, and VQ. We review and discuss the implementation of these algorithms. Initially, the colored image of any resolution is selected by the user which gets converted into grayscale image to be taken as an input image for both the techniques. Finally the Performance analysis of the image compression using self organized feature maps and JPEG 2000 Algorithm.
