Sobel Model

The Sobel model is a mathematical technique used in image processing to detect edges or boundaries within an image. It works by emphasizing areas where pixel values change sharply, which often indicates an edge. The model uses specific filters—small matrices that slide over the image—to calculate the intensity changes in horizontal and vertical directions. By combining these calculations, the Sobel model produces a new image highlighting the edges, helping in tasks like object recognition or image analysis. It’s a widely used method because it balances sensitivity to edges with noise reduction.
