Bawan Kumar, Ekambir Sidhu

Abstract


In this paper a brief description about image compression is being done using modified discrete Fourier transform. Further the proposed algorithm is then compared with the discrete cosine transform in terms of parameters like Compression, Time and Bit error rate.

Keywords
