OpenCV: Contour Features
WebIn this paper, we propose a convex-hull feature adaptation (CFA) approach for configuring convolutional features in accordance with oriented and densely packed object layouts. CFA is rooted in convex-hull feature representation, which defines a set of dynamically … WebApr 24, 2015 · The existing algorithm for convex hull is not able to capture the feature for a set of 3D points. Moreover, I found few mathematic tools have this function to obtain the concave hull and their responding points. ... A convex hull is unique, whereas there are many possible concave hulls. So you cannot say "the concave hull" but "a concave hull". higbee senior citizens center
