- 8 li j, gray r m . context-based multiscale classification of document images using wavelet coefficient distributions
顯然,這樣的做法在實際文檔中是完全行得通的。 - after the image lifting wavelet transformation, its coefficients have some characteristics, for example : the frequency compression characteristic, namely the primitive image energy majority of gathers to the low frequency sub-belt; spatial compression characteristic, namely high frequency sub-belt energy majority of centralisms in primitive corresponding and so on image edge, outline position; the coefficient distribution similarity, namely in the
經提升小波變換后,其系數具有如下特性:頻率壓縮特性,即原始圖像的能量大部分聚集到低頻子帶;空間壓縮特性,即高頻子帶的能量大部分集中在原始圖像的邊緣、輪廓等對應的位置;系數分布相似性,即同一方向上各級子帶系數幅值分布大體一致。 - an efficient algorithm is presented for constructing quantization tables of wavelet blocks with optimal bit allocations for a given image . the algorithm uses wavelet coefficient distribution statistics in a novel way, and pays attention to the traits of hvs . a dynamic programming strategy to produce optimal quantization tables over a wide range of bit rates is also adopted
該算法選用正交小波基對圖象做小波變換,然后重新組織小波系數成小波塊,用一種新的方式統(tǒng)計小波系數分布,并結合hvs的特點,采用動態(tài)策略在很大的比特率范圍內產生最優(yōu)的小波塊量化矩陣。 - 6 . based on wavelet coefficient distribution and a quantitative analysis on the magnitudes of wavelet coefficients, a new embedding strategy for watermarking is proposed based on dyadic discrete wavelet transform ( ddwt ) domain and multi _ band dwt domain ( mdwt ) respectively . it is claimed that different embedding formulae should be applied on the low frequency subband and high frequency subbands respectively
根據小波圖象系數的分布特點和對小波系數振幅的定性、定量分析,分別提出了基于離散二進小波變換(ddwt)和基于離散多進小波變換(mdwt)的新的圖象隱形水印嵌入對策;同時指出,水印嵌入到小波圖象低頻系數和高頻系數需要用不同的嵌入公式。 - It's difficult to find coefficient distribution in a sentence. 用coefficient distribution造句挺難的
