Method, computer-readable medium and apparatus estimating disparity of three view images

摘要

Provided is a method, computer-readable medium apparatus that may estimate a disparity of three view images. A global matching may be performed to calculate a global path by performing a dynamic programming on the three view images, and a local matching for supplementing an occlusion region of the calculated global path may be performed, and thereby a disparity estimation of the three view images may be performed.

主权项

1. An apparatus estimating a disparity of three view images, the apparatus comprising:
a global matching unit to calculate a first path in 3D coordinates where a cumulative value of a movement cost is a minimum by performing dynamic programming on three views, the three views corresponding to a left view, a center view, and a right view, to extract a disparity map and an occlusion map of each of the three views based on the first path; a local matching unit to perform the dynamic programming on two neighboring views of the three views to extract two disparity maps where an occlusion region of the disparity map is supplemented; and a final map calculation unit to calculate a final disparity map by combining the two disparity maps, wherein the 3D coordinates are obtained by configuring an x-axis value of each of the left view, the center view, and the right view to correspond to a value of each of a first-axis, a second-axis, and a third-axis of the 3D coordinates.
