Three-dimensional (3D) object recognition system using region of interest geometric features

A computer program product for object recognition, the computer program product comprising computer-readable instruction means stored on a non-transitory computer-readable medium that are executable by a computer for causing, the computer to perform operations of:

• receiving an implicit geometry representation regarding a three-dimensional (3D) object of interest;
• centering a region of interest (ROI) on the implicit geometry representation such that there is at least one intersection area between the ROI and the implicit geometry representation;
• calculating object shape features that reflect a location of the ROI with respect to the implicit geometry representation;
• assembling the object shape features into a feature vector;
• generating a classification confidence value with respect to a particular object classification;
• and
• classifying the 3D object of interest as a particular object upon the classification confidence value reaching a predetermined threshold.

A system for object recognition, the system comprising a memory module and a processor, wherein the memory module is encoded with instruction means that are executable by the processor for causing the processor to perform operations of:

• centering a region of interest (ROI) on the implicit geometry representation such that there is at least one intersection area between the ROI and the implicit geometry representation;
• calculating object shape features that reflect a location of the ROI with respect to the implicit geometry representation;
• assembling the object shape features into a feature vector;
• generating, a classification confidence value with respect to a particular object classification;
• and
• classifying the 3D object of interest as a particular object upon the classification confidence value reaching a predetermined threshold.
