Abstract
An apparatus and method for improved segmentation and object recognition which describes objects and background appropriately based on calculations of desired local surface geometries such as local surface orientation, local surface curvature, surface extent and occluding boundaries, from sensed relative range images. Relative range data is used rather than converting such data to absolute range and then performing the desired geometric calculations.
