Periodic clustered-dot screens are widely used for electrophotographic printers due to their print stability. However, moiré is a ubiquitous problem that arises in color printing due to the beating together of the clustered-dot, periodic halftone patterns that are used to represent different colorants. The traditional solution in the graphic arts and(More)
H.264/AVC belongs to block-based coding category. For the H.264/AVC intraframe coding, a frame is first divided into non-overlapped blocks, and then intra prediction and the DCT-like transform are applied block by block. For the inter frame coding, H.264/AVC employs variable-block-size for motion compensation and transform stages that can significantly(More)
