Using-Predictive-Filter

邻域平均法滤波 原图像画面清晰，添加勒椒盐噪声后图像上产生勒明显的黑色斑点（噪声），用不同模板的平滑滤波处理后图像上的噪声消失，但是图像变得模糊，并且，使用的模板越大，对图像的去噪效果越好，同时图像也变得越模糊。 (Neighborhood averaging filter clear picture of the original image, add the Le Salt and pepper noise generated after the image Roming noticeable black spots (noise), smoothing with different template processed image noise disappear, but the images become blurred, and the use of template bigger the better the image de-noising the same time, the image becomes more blurred.)

基于贝塞尔函数的虚拟阵列的角度估计，实现宽带信号的DOA估计(Based on the angle of the Bessel functions of the Virtual Array estimated broadband signal DOA estimation)

关于精致Lee滤波的原创matlab代码，只限仿真使用。代码详细，有说明，有图有结果。(About matlab code of the refined Lee filtering, Only simulation to use.)

A MATLAB based tool for determining number of clusters in a data set.

背景提取，迭代法(Surendra算法）；即采用帧差的方法，一帧图像减去前一帧图像，即可以对比得到图像中变化（移动）的区域，扣除移动的区域，即得到不动的背景。采用多帧图像迭代的方法，得到更加准确的背景。(Background extraction, iterative method (Surendra algorithm) frame difference method is used, an image by subtracting the previous frame, which can receive the image contrast change (movement) of the area, less the area of ​ ​ movement, that is obtained immovable background. Multi-frame image iteration method, to be more accurate background.)
