JPEG quantisation requires bit‐shifts only

A scheme for low power consumption JPEG quantisation is introduced. Multiplications and additions are not required – only bit‐shifting operations. A fully multiplierless JPEG‐like image encoding framework is also proposed, using a discrete cosine transform approximation. Simulations demonstrate that the introduced quantisation scheme produces a very low image degradation. The proposed architecture is also physically realised in FPGA technology.
