摘要：
An efficient 8 x 8 sparse orthogonal transform matrix is proposed for image compression by appropriately introducing some zeros in the 8 x 8 signed discrete cosine transform (SDCT) matrix. An algorithm for its fast computation is also developed. It is shown that the proposed transform provides a 25% reduction in the number of arithmetic operations with a performance in image compression that is much superior to that of the SDCT and comparable to that of the approximated discrete cosine transform.
