提出了一种用于多尺度边缘检测的小波变换滤波器系数的计算方法,并且以具体例子进行了检验,表明了该方法的有效性。
A method of calculating wavelet transformation filter coefficients for multiscale edge detection is given in this paper, and the efficiency of the method is clarified.
而传统的延拓方法在前后两个边界处都会产生伪边缘,并且在延拓时还需考虑滤波器系数长度的奇偶性。
But traditional border processing methods will cause false edges, and also should consider the parity of filter coefficient.
对比之下,H . 264是强度自适应的,基于DCT系数是否存在给定边缘的任何一边,和基于运动矢量差值和参考帧在边缘的差值。
H. 264's, by comparison, is strength-adaptive based on whether DCT coefficients exist on either side of a given edge and based on the motion vector delta and reference frame delta across said edge.
