Stereo Vision and 3D Reconstruction on a Distributed Memory System

An important research topic in image processing is stereo vision. The objective is to compute a 3-dimensional representation of some scenery from two 2-dimensional digital images. Constructing a 3-dimensional representation involves finding pairs of pixels from the two images which correspond to the same point in space. Several stereo matching algorithms are developed to find matching pairs. Hierarchical matching can be applied to improve the effectiveness and reliability of the matching algorithms. Hierarchy is established by multi-resolution images, also known as pyramids.
