The following interactive demos demonstrate various matching algorithms developed within the PROFI project, working on the MPEG-7 Core Experiment CE-Shape-1 test collection.

SIDESTEP This demo allows to select a matching method, and to generate various kinds of performance measures for a single query, a whole class, or the whole image collection.
Multiple Turning Angle Matching This demo allows to query with a number of polygonal curves, which are matched best to the contour of the image shape.
