Robust and Efficient Volumetric Occupancy Mapping

An algorithm for creating volumetric occupancy maps. This method was specifically designed to provide robust results when used in conjunction with noisy measurements, as they result from stereo matching.

An efficient sparse stereo analysis algorithm that applies a dense consistency check, leading to accurate matching results. Matching accuracy is further improved by the new feature detector exFAST, which is based on FAST but exhibits a less clustered feature distribution.



TeXGrapher is a free application for drawing graphs and exporting them into code for GraphTeX, a package for LaTeX which provides a collection of drawing macros. This package can be used for creating arbitrary drawings with LaTeX and provides a convenient way for specifying graphs within a LaTeX source file.
