Digital images are focused to a wide variety of distortions during processing, compression, storage and
reproduction any of which may cause in a dreadful condition of visual quality. Many systems use digital image
compression when it is needed to transmit or store the image. JPEG, JPEG 2000, WSQ compression is the most popular
image compression techniques but did not rebuild boundaries of an image perfectly. Here the new compression technique
is used. Sparse method such as KSVD and SPIHT algorithm are combined which gives better result rather than the
separately and K-SVD algorithm is used for dictionary creation It gives the better compression ratio
