"OpenCV provides four main types of blurring techniques. 1. Averaging This is done by convolving an image with a normalized box filter. It simply takes the average of all the pixels under the kernel area and replaces the central element. This is done by the function cv.blur () or cv.boxFilter (). Check the docs for … Ver mais Learn to: 1. Blur images with various low pass filters 2. Apply custom-made filters to images (2D convolution) Ver mais Image blurring is achieved by convolving the image with a low-pass filter kernel. It is useful for removing noise. It actually removes high frequency content (eg: noise, edges) from the image. So edges are blurred a little bit … Ver mais As in one-dimensional signals, images also can be filtered with various low-pass filters (LPF), high-pass filters (HPF), etc. LPF helps in removing noise, blurring images, etc. HPF … Ver mais " - Opencv blur image python
