WebA sliding neighborhood operation processes an image one pixel at a time, by applying an algorithm to each pixels neighborhood. In distinct block processing, an image is divided into equally-sized blocks without overlap, and the algorithm is applied to each distinct block. The neighborhoods and blocks are then reassembled to form the output image. WebJun 12, 2024 · Custom Image Spatial Filtering Code using loops...
