compression artifact

常見例句

However, in the compression process of blocking image data, severe boundary artifact will be produced because of boundary extension and coefficient quantification.
但在分塊處理過程中，由于小波變換的邊界擴展及系數(shù)量化等原因會產(chǎn)生較嚴(yán)重的邊緣贗像效應(yīng)。
Blocking artifact is evident in the reconstructed image especially when the compression ratio is high. A new adaptive de-blocking algorithm on spatial domain is proposed.
塊效應(yīng)在低比特率圖像中極為明顯，提出一種基于方塊方向活動性的自適應(yīng)空域去塊效應(yīng)算法。
