说明：  根据签名骨架和二值签名，提取了签名图像的笔划宽度直方图。(extracte the stroke width historgram of signature images)

说明：  直方图添加与去除椒盐噪声和高斯噪声并进行对比，以及直方图均衡化的matlab程序实现代码 (Add the histogram and remove the salt and pepper noise and Gaussian noise and contrast, and histogram equalization matlab program code)

说明：  通过调用IIR5函数对所给的信号进行滤波，其中通过fdatool 设计的直接1型切比雪夫滤波器的参数保存在coefficients1.mat文件中。(by calling IIR5 function as a signal to the filter, which it adopted fdatool design a direct-Chebyshev filter parameters stored in coefficients1.mat document.)

使用自然梯度盲分离算法，实现对四个亚高斯信号的分离，并从分离结果可总结出盲分离算法的两个不确定性。同时给出了串音误差。(Blind separation using the natural gradient algorithm to achieve the separation of the four sub-Gaussian signals, and the separation results can be summarized from the blind separation algorithm of two uncertainty. Crosstalk error is also given.)
