An integral criterion for detecting boundary edges and textured regions

Abstract:

Edge maps which are computed from textured scenes using existing methods based on local image analysis are not very meaningful. This is because edges at object boundaries are not differentiated from edges in texture. We introduce a real-time algorithm that overcomes this difficulty by computing the Direchlet integral in a small image patch at different scales. These measurements are combined and interpreted in a probabilistic framework avoiding the need to threshold. As a result the output of...
