Concept
Canny edge
Canny edge detection is a classic algorithm (John Canny, 1986) that extracts thin, connected outlines from an image. Think of it like a Sobel gradient filter, except with three extra stages that clean up the output into single-pixel lines instead of thick, noisy blobs.
The rest of “Canny edge” is a premium feature: every concept in the library gets a precise, practitioner-focused write-up like this one, cross-linked straight from the paper summaries that use it.
