In forward algorithm , we according to the high level coefficients to locate the jumps and modify the coarser level coefficients , which relate with the jumps . in inverse transforms algorithm , according to the locations to modify the datum , which relate with the jumps . we can reconstruct the image well by using this algorithm , and avoid the gibbs " phenomenon completely 該算法不必修改雙正交小波變換及其濾波器系數(shù),在小波圖像分解時只是根據(jù)高頻小波系數(shù)定位圖像的跳躍處,修改關(guān)聯(lián)跳躍處的粗尺度小波系數(shù);重構(gòu)時根據(jù)算法修改關(guān)聯(lián)跳躍處的重構(gòu)數(shù)據(jù),就能很好地重構(gòu)原圖像,并從本質(zhì)上消除了gibbs ’現(xiàn)象。
