In computer graphics, vectorization is the conversion of raster graphics into vector graphics, a process also known as image tracing.


Unlike the opposite process rasterization, vectorization is not well defined, meaning there is not a 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.
