Abstract: According to some embodiments, an imaging processing method for extracting a plurality of planar surfaces from a depth map includes computing a depth change indication map (DCI) from a depth map in accordance with a smoothness threshold. The imaging processing method further includes recursively extracting a plurality of planar region from the depth map, wherein the size of each planar region is dynamically adjusted according to the DCI. The imaging processing method further includes clustering the extracted planar regions into a plurality of groups in accordance with a distance function; and growing each group to generate pixel-wise segmentation results and inlier points statistics simultaneously.

Abstract: A method for approximately solving a consensus set maximization (“CSM”) problem for a dataset is disclosed. The method comprises relaxing a maximum fitting residual constraint in the CSM problem to an average error bounded constraint; defining a plurality of decision problems related to the relaxed CSM problem; solving each decision problem by defining an optimization problem; and selecting a consensus size for the CSM problem based on solutions to the decision problems.
