An algorithm that extracts image edges through several careful steps.
Canny is like a very neat kid with a coloring book. It ignores the smudges, then traces the real outlines in black.
It is a classic Computer Vision tool. It helps programs see borders before segmentation or line finding.
Computer Vision
Canny is a classic edge detector in Computer Vision.
Hough Transform
Canny often finds edges first, then Hough Transform finds lines or circles.
Image Segmentation
Canny edge maps can help Image Segmentation find object borders.
