Description: 利用傅里叶变换，对图像进行低通滤波处理，利用sin函数窗-To avoid boundary artifacts and estimate really the frequency content of the image (and not of the artifacts!), one needs to multiply M by a smooth windowing function h and compute fft2(M.*h). Use a sine windowing function. Can you interpret the resulting filter ?
