Detection of Points of Interest for Geodesic Contours - Application on Road Images for Crack Detection

A new algorithm of automatic extraction of thin structures in textured images is introduced, and, more specifically, is applied to detection of road cracks. The method is based on two steps: the first one consists in detecting points of interest inside the thin structure whereas the second step connects the points with a geodesic contour process. The main contribution of this work is the study of automatic detection of points of interest inside thin structures in a high-textured background. The results are compared with a Markovian segmentation.
