Class Information
Number: 382/268
Name: Image analysis > Image enhancement or restoration > Edge or contour enhancement > Minimize discontinuities at boundaries of image blocks (i.e., reducing blocking effects or effects of wrap-around)
Description: Subject matter including means or processes to smooth undesirable transitions at the boundaries separating discrete pixel* blocks after the blocks have undergone processing such as compression or decompression, or to process pixel*s at the edges of an image when the process requires neighboring or context pixel*s.
