Apparatus and method for performing segment-based disparity decomposition

摘要

A method and system for generating a disparity map. The method comprises the steps of generating a first disparity map based upon a first image and a second image acquired at a first time, acquiring at least a third image and a fourth image at a second time, and determining one or more portions comprising a difference between one of the first and second images and a corresponding one of the third and fourth images. A disparity map update is generated for the one or more determined portions, and a disparity map is generated based upon the third image and the fourth image by combining the disparity map update and the first disparity map.

1. A method for performing segment-based disparity decomposition, comprising the steps of:
generating a left image from one of a stereo pair of image capture devices; determining one or more segments present in the left image; generating a right image from the other of the stereo pair of image capture devices; shifting one of the left and right images by one pixel; subtracting the shifted image from the other of the left and right images to form a difference image; determining a temporal stability associated with each of the one or more segments; determining a disparity value only for the one or more segments having been determined as temporally unstable in accordance with the difference image; and updating the portions of a disparity map corresponding to the determined disparity value for the one or more temporally unstable segments.
