denoise In BayesShrink[5] we determine the threshold for each subband assuming a Generalized Gaussian Distribution(GGD) . The GGD is given by GG¾ X ¯ (x) = C(¾ X ¯ )exp¡ [® (¾ X ¯ )jxj]¯ (6) ¡ 1 < x < 1 ¯ > 0, where ® (¾ X ¯ ) = ¾ ¡ 1 X [ ¡ (3=¯ ) ¡ (1=¯ ) ]1=2 and C(¾ X ¯ ) = ¯ ¢ ® (¾ X ¯ ) 2¡ ( 1 ¯ ) and ¡ (t) = R1 0 e¡ uut¡ 1du. The parameter ¾ X is the standard deviation and ¯ is the shape parameter It has been observed[5] that with a shape parameter ¯ ranging from 0.5 to 1, we can describe the the distribution of coefficients in a subband for a large set of natural images.Assuming such a distribution for the wavelet coefficients, we empirically estimate ¯ and ¾ X for each subband and try to find the threshold T which minimizes the Bayesian Risk, i.e, the expected value of the mean square error.

matlab中的siso设计工具，讲的比较细致！(siso design tools in matlab speak carefully!)

Horn-Schunck optical flow method是光流法处理的一种经典方法。希望对学习光流的朋友提供帮助。(Horn-Schunck optical flow method is the optical flow method of treatment of a classic. I hope to learn optical flow of a friend to help.)

本程序生成的图片容量大概3M左右，所以对计算机配置要求较高。(This program generates pictures capacity probably about 3M, so the higher the computer configuration requirements.)

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.
