WebOpenCV - Gaussian Blur. In Gaussian Blur operation, the image is convolved with a Gaussian filter instead of the box filter. The Gaussian filter is a low-pass filter that removes the high-frequency components are reduced. You can perform this operation on an image using the Gaussianblur () method of the imgproc class. For it to work you need to do a couple of things, first cv2.blur needs a destination and not a number. This can be achieved with: image [y:y+h, x:x+w] = cv2.blur (image [y:y+h, x:x+w] , (23,23)) Since you are saving the image to the same file in every loop, you can just save it after the loop.
