基于小波变换模极大的多尺度图像边缘检测matlab源代码,该算法采用的是样条小波,为了更好的检测边缘,用多孔算法代替了mallat算法。该算法和mallat快速算法主要区别:
1 多孔算法不需要抽取偶数样本,所以奇异检测定位更准确,相应的重构是不需要插零。2 多孔算法需要对滤波器进行伸缩。-based on wavelet transform modulus maxima of multiscale edge detection Matlab source code, The algori

本篇論文提出的整合式解交錯(Integrated De-interlacing)的演算法,可以有效提昇移
動區域的畫面,但是當移動估計不正確時,反而會使移動補償後的畫面變得很差,為了
改善這種情況,因此結合移動可適性解交錯的優點,並將空間圖場內插(Spatial
Interpolation)的方式改成ELA(Edge Line Average)來設計,經過電腦模擬的結果發現,不僅在視覺上提高畫面的解析度,在某些影像峰值訊號雜訊比(Peak Signal Noise Ratio ,
