A Review on Image Compression Techniques

Abstract: Fractal image compression (FIC) is very useful in situation, where we have to deal with Chunk of data with limited storage space and low band width. This lossy compression technique gives a high compression ratio by representing the image in a vector form representation. Main drawback of standard image compression techniques of JPEG and JPEG 2000 are resolution dependent and poor PSNR value at high compression ratio. This lossy compression technique provides good trade off between PSNR value and compression ratio. In this survey paper different image compression techniques are compared.
