Image Compression Algorithm Using Two Dimensional Discrete Cosine Transform

Abstract: In this proposed work the two dimensional discrete cosine transform is used for image compression. This transforms process the signal in frequency domain. The significant feature of discrete cosine transform is to store the most of the information in lower frequency components. The performance of proposed technique over existing technique is superior. PSNR is considered quality check parameters in image compression. Keywords: Image compression, fractional transform, discrete cosine transform
