Comparative analysis of FFT and DCT performances in image compression And evaluation of their performances

Dr Nssr Murthy, Dr Iv Muralikrishna

Abstract :

<p> Compression of images is an important task for Data compression in digital image processing . It reduces redundancies in data so that data storage requirements will be minimized and there by cost for storing data also will be reduced . This is equivalent to increasing capacity of the storage medium and helps in efficient transmission of data at lower costs. . Development of efficient compression techniques is very important for this . There are so many tools to compress data efficiently. This paper tries to analyse and study various image compression techniques . There are different techniques in image compression of an digital image which includes DFT, FFT, DCT , DWT.Wavelets and fractal compression etc, each one of them has an advantage in their domain. This paper tries to compare and analyse DFT and FFT transforms and their applications to image compression.</p>
