已知代码如下:[br][/br]face = misc.face()[br][/br]blurred_face1 = ndimage.gaussian_filter(face, sigma=1)[br][/br]blurred_face3 = ndimage.gaussian_filter(face, sigma=3)[br][/br]sharp_face = blurred_face3 +6*(blurred_face3-blurred_face1)[br][/br]blurred_face1和blurred_face3都是对face的平滑处理,通过相减,让相似的值变小,再通过乘以6,增加两极差距,实现边缘锐化。
