Detection of Interest Points on 3D Data: Extending the Harris Operator
We consider a problem of interest point detection, i.e. location of points with standing out neighborhood, for a 3D mesh data. Our research is motivated by the need of general, robust characterization of a complexity of the mesh fragment, to be used for mesh segmentation and description methods. We analyze the reasoning behind traditional Harris operator for 2D images  and propose several possible extensions to 3D data. We investigate their performance on several sets of data obtained with laser digitizer.
