Review of Increasing Image Compression Rate using (DWT+DCT) and Steganography


The goal of image compression is to remove the redundancies for minimizing the number of bits required to represent an image while any type of compression like DWT,DCT,DFT, steganography works by embedding the secret data in redundancies of the image in invisibility manner. In this paper we increase image compression is done by hybrid (DCT+DWT) transform… (More)
