IMAGE MATCHING APPARATUS AND METHOD
First Claim
1. An image matching apparatus, comprising:
- a determining unit determining whether a node, in which a first pixel of a left image of a subject and a second pixel of a right image of the subject corresponding to the first pixel are calculated, is a matchable region; and
an operating unit calculating a disparity value by using the brightness information of a left window composed of the first pixel corresponding to the node and peripheral pixels surrounding the first pixel and the brightness information of a right window composed of the second pixel corresponding to the node and peripheral pixels surrounding the second pixel, when the node is the matchable region as a result of the determination.

9. An image matching apparatus, comprising:
-
a unit processing unit performing Sum of Absolute Difference (SAD) and Received Mean Census Transform (RMCT) on brightness information of left and right images to calculate an energy value of each node in an synthesis image of the left and right images; a multi-processing unit calculating a matching value of a stereo image per each line by using the energy value of the each node; and a rear processing unit calculating a disparity value of the stereo image by using the matching value. - View Dependent Claims (10, 11, 12, 13)

14. An image matching method, comprising:
-
determining whether a corresponding node, in which a first pixel of a left image of a subject and a second pixel of a right image of the subject corresponding to the first pixel are calculated, is a matchable region; and calculating an energy value of the corresponding node by using the brightness information of a left window composed of the first pixel corresponding to a node and peripheral pixels surrounding the first pixel and the brightness information of a right window composed of the second pixel corresponding to the node and peripheral pixels surrounding the second pixel, when the first and second pixels are the matchable region as a result of the determination. - View Dependent Claims (15, 16, 17, 18, 19)
