维纳滤波对图像去噪与最小二乘方滤波对图像去噪的比较-Wiener filter for image denoising with the least squares filter for image denoising comparison

本程序实现了基于质心法的目标跟踪，由于算法比较简单，因此背景颜色必须简单，最好是纯白色的。本程序先经过对视频图像的灰度化，二值化等一些图像处理，然后找出质心。程序中用到了Opencv库函数-Realize this procedure based on the quality of target tracking-force, due to relatively simple algorithm, so the need for a simple background color, the best was pure white. This procedure, after the first video images of gray and binary image processing, such as, and then find the center of mass. Procedures used in the library function Opencv

canny检测器是很有效的边缘检测器，该函数可以实现对目标图像的边缘提取。该方法总结如下：1.图像使用带有指定标准差的高斯滤波器来平滑，以此减少噪声；2.在每一点计算局部梯度和边缘方向；3.第二步中确定的边缘点会导致梯度幅度图像中出现脊，然后追踪所有脊的顶部，并将所有不再脊顶部的像素设置为0；4.执行边缘链接-canny detector is very effective edge detector, this function can be achieved on the target image edge detection. This method is summarized as follows: 1. Image used with the specified standard deviation of the Gaussian filter to smooth out, thereby reducing the noise 2. In the calculation of each point of local gradient and edge direction 3. The second step in determining the edge points will led to the image gradient magnitude ridge appears, and then keep track of all of the top of the ridge, and ridge at the top of all the pixels are no longer set to 0 4. the implementation of the edge link
