harry角点检测c++源代码，利用差分算子对图像进行滤波，对Ix2/Iy2/Ixy进行高斯平滑，以去除噪声，计算角点量，进行局部非极大值抑制以获得最终角点-harry corner detection c++ source code, the use of differential operators on image filtering, Gaussian smoothing of Ix2/Iy2/Ixy to remove noise, calculate the amount of corners, the local non-maxima suppression to get the final corner
