Adaptive image segmentation by combining photometric invariant region and edge information
Theo Gevers · IEEE Transactions on Pattern Analysis and Machine Intelligence · 2002
An adaptive image segmentation scheme is proposed employing the Delaunay triangulation for image splitting. The tessellation grid of the Delaunay triangulation is adapted to the semantics of the image data by combining region and edge information. To achieve robustness against imaging conditions (e.g. shading, shadows, illumination and highlights), photometric invariant similarity measures and edge computation are proposed. Experimental results on synthetic and real images show that the segmentation method is robust to edge orientation, partially weak object boundaries and noisy-but-homogeneous regions. Furthermore, the method is robust, to a large degree, to varying imaging conditions.
