👉 In computer graphics and image processing, a "patchwise" approach is a method of assigning pixel values to an image based on a set of predefined pixel values or criteria. This technique involves selecting a small number of pixels from each region of the image, calculating the weighted sum of these pixels, and then applying a value to that pixel. The goal of patchwise processing is to reduce computational complexity by efficiently computing the desired output in a single pass through the image. In practice, patches are often used
