Abstract: In general, the invention includes a method and system of rectangular solid detection comprising: receiving an image of data; detecting edges from the image of data; finding lines from the image of data; finding junctions from the lines; filtering junctions and lines that meet a first set of certain criteria; grouping the junctions and lines that meet a second set of certain criteria; and detecting whether a rectangular solid exists in the image according to the grouping. The criteria includes using triplets of lines and fork junctions. The system and method may also analyze a single frame, or a single frame paired with a reference frame.

Abstract: A system and method for obtaining salient contours from two-dimensional images acquired by a sensor is disclosed which process the two-dimensional images with an edge detector to produce edgels from each of the images, link the edgels into lists known as contours, compute a saliency value for each of the contours, rank the contours in decreasing order of saliency, and select certain ones of the ranked contours based on the requirements of a particular vision application.Other devices, systems and methods are also disclosed.
