WitrynaFor this reason, blurring is often referred to as smoothing. To remove a distracting background, you might intentionally blur portions of an image, as is done in ‘Portrait’ mode, on mobile device cameras. Being a fundamental processing technique in Computer Vision, filtering images with kernels has many more applications. hilde show https://mickhillmedia.com
