- - AN EFFICIENT TABLE-LOOKUP BASED VISUALLY-LOSSLESS IMAGE COMPRESSION SCHEME

摘要

There is one image compression structure models the human visual perception structures shown. Visually-lossless according to the structure, using the quantization error value of the image, the image is compressed (130) to the naked eye can not be visually distinguished from the original image. To aid in image compression in a portable device such as a digital camera, the quantization look-is (precoupled) connected to the pre-up table.
