IWCD-PROPOSED IMAGE COMPRESSION METHOD BASED ON INTEGER WAVELET AND DCT

Abstract

This paper describes a new lossy image compression decompression algorithm. In lossy compression techniques there are some loss of information, and image cannot be reconstructed exactly.This algorithm will be referred to as (IWDC), which stands for integer wavelet (IWT) and discrete cosine transform (DCT) and this algorithm improves existing techniques and develops new image compressors.(IWDC) is efficient than corresponding DCT and wavelet transform functions and incorporating DCT and integer wavelet transform are shown to improve the performance of the DCT and integer wavelet (IWT). In the new proposed compression is more efficient than the still image compression methods.
