3D data

Their system shows quick recognition times for multi-objectscenes using a data base of fifteen Lacoste Polo Shirts with high accuracy. Johnson and Hebert (1999) alsoused point features for object recovering, they used “spin images” which could be considered as2D histograms of the surface locations around a point. The spin image is generated using thenormal to the selected point and rotating a cutting plane around the point using the normal as therotation Cheap Lacoste Polo Shirts. As the plane spins around the point, the intersections between the plane and thesurface are used to index a 2D histogram. The bins in the histogram represent the amount ofsurface a particular patch of the cutting plane intersects the object. Spin images are used toestablish correspondence between scene and model points for 3D Lacoste Shirts.
