Sobel-Feldman filter: Edge Detection and Gradient Extraction

WebThe Sobel operator, sometimes called the Sobel–Feldman operatoror Sobel filter, is used in image processingand computer vision, particularly within edge detectionalgorithms where it creates an image emphasising edges. It is named after Irwin Sobeland Gary Feldman, colleagues at the Stanford Artificial Intelligence Laboratory(SAIL).
