In computer graphics, vectorization refers to the process of converting raster graphics into vector graphics.

Popular applications [edit]
- In computer-aided design (CAD) drawings (blueprints etc.) are scanned, vectorized and written as CAD files in a process called paper-to-CAD conversion or drawing conversion.
- In geographic information systems (GIS) satellite or aerial images are vectorized to create maps.
- In graphic design and photography, graphics can be vectorized for easier usage and resizing.
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.

Vectorization algorithms [edit]
Classic edge detection methods are for example Roberts Cross, Canny edge detector and Sobel.
