Curvature

LineCurvature2D, This function calculates the curvature of a 2D line. It first fits polygons to the points. Then calculates the analytical curvature from the polygons. K = LineCurvature2D(Vertices,Lines) inputs, Vertices : A M x 2 list of line points. (optional) Lines : A N x 2 list of line...

This function calculates the principal curvature directions and values of a triangulated mesh. The function first rotates the data so the normal of the current vertex becomes [-1 0 0], so we can describe the data by XY instead of XYZ. Secondly it fits a least-squares quadratic patch to the local...

CORNER works by the following step:1. Apply the Canny edge detector to the grey level image and obtain a binary edge-map.2. Extract the edge contours from the edge-map, fill the gaps in the contours.3. Compute curvature at a low scale for each contour to retain all true corners.All of the...
