16. The method as set forth in claim 9 , further comprising acts of: performing an object specific search of salient 2D (x, y) locations within the implicit representations to generate candidate ROIs; performing, an object specific search of salient locations in (x, y) and altitude (z) if required for the 3D object of interest to generate candidate ROIs; applying object classifiers to classify the 3D object of interest as a particular object upon the output of the object classifiers reaching a predetermined threshold; determining if a spatial search is completed within the implicit representation so that there remains no unsearched portions of the implicit representation; if yes, determining if the 3D object of interest is the last object of interest the implicit representations; if yes, then providing a user the classifications of the recognized objects and stopping; if no, then selecting a next object of interest within the implicit representations and repeating the process above beginning with performing an object specific search; and if no, then updating search parameters with the unsearched portions of the implicit representation and repeating the process above beginning with performing an object specific search.
9. A computer implemented method for object recognition in colorized point clouds, comprising: an act of causing a computer having a processor to perform acts of: receiving, in an implicit geometry engine, a three-dimensional (3D) colorized point cloud data regarding a 3D object of interest, to convert the point cloud data into implicit representations, and to generate geometric features; generating, in a geometric grammar block, object cues and recognizing geometric objects using geometric tokens and finite state machines; generating, in a visual attention cueing block, object cues based on two-dimensional (2D) visually salient properties; performing, in an object recognition block, a local search for objects using cues from the cueing block and the geometric grammar block; and classifying the 3D object of interest as a particular object upon a classifier reaching a predetermined threshold.
