Abstract
As the first step in the development of a signal compression method for 3-dimensional television systems, the method of searching for disparity between the right and left images has been studied. To increase the accuracy of matching between the distinctive points of the right and left images, two characteristics of the visual system of the human beings have been introduced ; one is the sensitiveness to the contour of the objects and the other is the nonlinearity of the sensitivity to the intensity of the light.Experiment results show that an optimized matching method called “Rubber-matching” is about nime times more accurate than the conventional block-matching, and about three times more accurate than a high-accuracy matching method using phase correlation.
