Ridges and Valleys Detection in Images using Difference of Rotating Half Smoothing Filters
Résumé
Inthispaperweproposeanewridge/valleydetectionmethod in images based on the difference of rotating Gaussian semi filters. The novelty of this approach resides in the mixing of ideas coming both from directional filters and DoG method. We obtain a new ridge/valley anisotropic DoG detector enabling very precise detection of ridge/valley points. Moreover, this detector performs correctly at crest lines even if highly bended, and is precise on junctions. This detector has been tested successfully on various image types presenting difficult problems for clas- sical ridges/valleys detection methods.
