N2 - In this paper, we propose a modified hybrid DCT-SVD image-coding system (MHDCTSVD) to encode both monochromatic and color images. The color (RGB) components are transformed into YCbCr. Cb and Cr components are downsampled by a factor of two along both the horizontal and vertical directions. The standard deviation of 8×8 blocks of the Y component is used to select between DCT and SVD. The DCT is used to transform the highly correlated blocks of the YCbCr components, while the SVD is used to transform the low correlated blocks. The simulation results show good image quality at low bit rates compare with the conventional hybrid DCT-SVD image-coding algorithm.
