IIR FILTER

详细表述了分数阶傅立叶变换的离散实现，将现有的算法进行比较。-In this note we make a critical comparison of some matlab programs for the digital computation of the fractional Fourier transform that are freely available and we describe our own implementation that lters the best out of the existing ones. Two types of transforms are considered: First the fast approximate fractional Fourier transform algorithm for which two algorithms are available. The method is described in H.M. Ozaktas, M.A. Kutay, and G. Bozdagi. Digital computation of the fractional Fourier transform. IEEE Trans. Signal Process., 44:2141{2150, 1996. There are two implementations: one is written by A.M. Kutay the other is part of package written by J. O Neill. Secondly the discrete fractional Fourier transform algorithm described in the master thesis C . Candan. The discrete fractional Fourier transform, Bilkent Univ., 1998 and an algorithm described by S.C. Pei, M.H. Yeh, and C.C Tseng: Digital fractional Fourier transform base

图像阈值分割---迭代算法 1.处理流程：        1.为全局阈值选择一个初始估计值T(图像的平均灰度)。        2.用T分割图像。产生两组像素：G1有灰度值大于T的像素组成，G2有小于等于T像素组成。        3.计算G1和G2像素的平均灰度值m1和m2；        4.计算一个新的阈值:T = (m1 + m2) / 2;        5.重复步骤2和4,直到连续迭代中的T值间的差小于一个预定义参数为止。     &
