The Discrete Cosine Transform (DCT) is widely used in image compression for its high power compaction property. The Signed DCT (SDCT) and its modifications approximate the DCT and proceed faster. This paper introduces an efficient and low complexity 8 point transform. The proposed algorithm is derived by applying the signum function operator to an existing(More)
Real time imaging is essential for internet multimedia and modern satellite communications. Discrete Cosine Transform (DCT) is the core for image processing such as image compression and coding for its high power compaction property. The Signed DCT (SDCT) and its modifications approximate the DCT while requiring much less number of arithmetic operations(More)
