Image Compression Using Wavelet Technique

Image compression is now essential for applications such as transmission and storage in data bases. A variety of new and powerful algorithms have been developed for image compression over the years. Among them the wavelet-based image compression schemes have gained much popularity due to their overlapping nature which reduces the blocking artifacts that are common phenomena in JPEG compression and multiresolution character which leads to superior energy compaction with high quality reconstructed images. In this paper we discuss about the image compression, wavelet based techniques and algorithm of image compression.
