Abstract

A method and apparatus provide a technique for generating a mesh based on an image view. The mesh includes a plurality of trapezoidal patches which can be used in a comparison operation with regard to a second co-planar image view. The comparison operation extracts disparity information between the patches of the respective images and these disparities can be used to calculate depth estimations for objects within the image of use.
