Opencv gaussian filter

WebThis function uses the Difference of Gaussians method for applying band-pass filters to multi-dimensional arrays. The input array is blurred with two Gaussian kernels of differing sigmas to produce two intermediate, filtered images. WebIn this chapter, we apply Gaussian filter to an image that blurs an image. We are going to use OpenCV function GaussianBlur to apply Gaussian filter to images. It can be found under Imgproc package. Its syntax is given below −. Imgproc.GaussianBlur (source, destination,Size,SigmaX); The function arguments are described below −. Sr.No.
