Robust depth-map estimation from image sequences with precise camera operation parameters

The depth-map of a scene conveys the fundamental information that is extremely useful for object segmentation, compact representation of videos, etc. We present an algorithm for robust depth-map estimation from image sequences with precise camera operation parameters. This algorithm exploits precise camera operation parameters to find correspondence points among multiple frames of an image sequence of a static scene. Our algorithm is able to deal with arbitrary camera movement. The experimental results show significant improvement in the accuracy of depth-maps compared with the conventional two-frame matching method.
