GMX-PhotoPainter is a standalone application that transforms an image (generally a photo) into an original artwork. With it, artists can start with an existing picture such as from a digital camera or scanner, a 3D rendering or painting from another program or imaging application. Gertrudis first performs a topological analysis of the image’s content and builds a matrix of flow direction vectors. Users can then paint a few quick strokes across the desired features of their image. GMX-PhotoPainter uses this information to generate something that looks more like hand-drawn masterpieces.
