Abstract
The present invention relates to an image/video enhancement system and method for transmission of the image/video. The system processes an image before transmission using a pre-processor and then de-processes it after transmission using a post-processor. The pre-processor increases the compression ratio of the compression scheme used by the transmission system without losing image quality. The post-processor restores the transmitted image to a high-quality image.
