Curvatures

1. Find the edge image using the Canny edge detector.2. Extract edges (curves) from the edge image: 2a. fill gaps if they are within a range and select long edges, 2b. find T-junctions and mark them as T-corners. 2c. obtain the `status' of each selected edge ${Gamma}$ as either `loop' or...

Two vein extraction methods as described by Miura et al. for finger vein authentication.Maximum curvature:This method will try to extract the centre lines of the veins. This is done by calculating local maximum curvatures in cross-sectional profiles of a vein image. The method is supposed to be... Platforms: Matlab
