What Does Edge Detection Do?
Edge detection identifies boundaries between different regions of an image, turning a photo into a sketch‑like representation. It's widely used in computer vision, but also for creative effects – converting photos to line art, highlighting architectural details, or preparing images for coloring books. Our tool uses a built‑in GD filter to extract edges and then amplifies them based on your chosen threshold.
