发明名称 METHOD AND APPARATUS FOR REDUCTION OF IMAGE DATA COMPRESSION NOISE
摘要 An image encoding module (35) and an image decoding module (37) provide a method of performing transform coding of an original image source (31), where the method serves to suppress or eliminate blocking artifacts. Encoded data (59) are transmitted by the image encoding module (35), converted into received data (83), and transformed into modified data (85) by means of a filtering operation (95) utilizing quantization error terms (79). The quantization error terms (79) can be derived from quantization error data generated in the image encoding module (35), or can be provided as a look-up table (109) in an alternative image decoding module (101). The modified data (85) are converted into reduced-noise image data (89) for reconstruction into a digital image (41).
