从曲线中检测到其峰值：先利用二次求导得到所有凸点，设置门限，去除过低的凸点，然后利用滑动窗的方法，在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

This function calculates the radial derivative of an input image. Input parameters: inputImage - the image to calculate the derivative from radialFilterLength - the length of the filter to use, total length will be 2*radialFilterLength+1 centerX and centerY - the point that is considered the center of the image, for the calculation minRadius and maxRadius - the minimum and maximum radius to calculate the angular derivative for. radialApproach - set to 1 to use a radius and angle search method, or 0 for a per-pixel approach
