Abstract

The present embodiments provide for automatically detecting the location and severity of occluded regions within input data. A grid representation of a scene is generated from a data set, characterizing spaces of the grid representation as free, occupied, and hidden/occluded. The grid is bounded, and a connected component analysis is performed on the hidden space to identify the occluded regions.
