光伏BP预测

there are two parts in these codes. the first implements an eight point algorithm which is used to compute the fundamental matrix in computer vision. the second is used to compute the optical flow and the unreliable region.

该代码实现了图像的滤波处理，这段代码给出了三种滤波矩阵，包括图像平滑(低通滤波器)、图像边缘提取(高通滤波器)等。用户下载后可以根据自己需要修改滤波矩阵和参数值，以便实现特殊的功能。为了形象的说明滤波效果，代码执行后可以看到滤波前后滤波后的对比图像。 (The code of the image filter processing, the code shows the three filter matrix, including the smoothing (low pass filter), image edge detection (high-pass filter) and so on. Users can download their own need to modify the filter matrix and the parameter values in order to achieve a specific function. Filtering effect to the image description, code execution before and after filtering can be seen after comparison of the filtered images.)
