AN APPROACH FOR COLOR IMAGE COMPRESSION OF BMP AND TIFF IMAGES USING DCT AND DWT

Now a days image compression has become is an indispensible part of digitized image storage and transmission. Compression of an image i s necessary before storing and transmitting it due to its limitation of storage and bandwidth capacity. Wavelet transform decomposes complexion of images into its elementary forms. In this paper, a comparative study has been carried out on image compression using DCT (Discrete Cosine Transform) and DWT (Discrete Wavelet Transform). A comparison is outlined to emphasize the results of this compression system between DCT and DWT using BMP (Bitmap Image) and TIFF (Tag Index File Format) color images.
