We propose an image-coding algorithm which combines the discrete cosine transform (DCT) and the singular value decomposition (SVD). The DCT is used to transform those blocks in the source image that exhibit a high correlation, while blocks with greater high-frequency content are transformed using the SVD. A simple criterion is used to decide which transform should be used on each block. Simulation results show that the new hybrid algorithm provides good distortion, bit rate, and image quality-especially in images which are less spatially correlated
