In the traditional wavelet transform, because the wavelet filter and coefficient is fixed, as a result, when the discontinuous signal is analyzed, it will produce a lot of big wavelet coefficients in the transition, which makes against the compression. in the image processing, some image is roughness, and it may has sharp edges and oddity parts
由於傳統小波變換的濾波器長度和系數是固定不變的，不能適應輸入信號而變化，這使得在分析非連續信號時，在躍變點兩側會產生大的小波系數;對具有尖銳邊緣、分段光滑或奇異點、圖文混合圖像處理效果很差。
