• Reducing JPEG distortion

    Filtering and edge enhancement have been applied to restoring images that have been distorted due to lossy image compression. But these techniques have ignored a feature of digital compression--the fact that the sender has access to both the original and the distorted images, enabling the encoder to transmit information specifying the regions where the enhancement was successful.
