Arkan is designed to convert border of a raster mask (selection of an object in scene) or any closed polyline into B-spline (piecewise cubic Bezier curve) representation spread widely in vector graphics packages. Arkan chooses the best position both for node points (junctions of adjacent Bezier polynomial pieces) and for control points, which don’t lie on the curve but only affect its shape. Minimum description length approach powers the program. In addition to its unique outlining capabilities Arkan features nice and friendly user interface
It’s typical task in computer graphics to describe contour of raster masks in terms of a set of cubic Bezier curves. For example, to allow changing (interpolation) of the mask during the time in a compositing environment, such as Adobe After Effects. Currently this task is performed manually for many frames and it’s really painful even for a skilled computer designer.
