In computer graphics, image tracing or vectorization is the conversion of raster graphics into vector graphics.

Examples[edit]

Unlike the opposite process, rasterization, vectorization is not well defined, meaning there is no single "correct" method. Many different algorithms exist, and each gives different results, as vector representations are more abstract than pixels. The following tracing examples of a hard to vectorize photo illustrate these limits.

Vectorization algorithms[edit]

Classic edge detection methods are for example Roberts Cross, Canny edge detector and Sobel.
