First, the Gaussian kernel is linearly separable. This means we can break any 2-d filter into two 1-d filters. Because of this, the computational complexity is reduced from O(n2) to O(n). Let’s see an example Applying multiple successive Gaussian kernels is equivalent to applying a sing...

In thisOpenCV Python Tutorial, we have learned how to blur or smooth an image using the Gaussian Filter.
可以看出高斯效果好点,不过还是要根据不同的需求去做的。 使用cv2.GaussianBlur函数应用高斯滤波,详细用法请参考:OpenCc GaussianBlur方法 使用cv2.medianBlur函数应用中值模糊,详细用法请参考:OpenCV medianBlur方法 使用cv2.bilateralFilter函数应用双边滤波,详细用法请参考:OpenCV bilateralFilter方法...
