Patent number: 8744169Abstract: Methods and systems for egomotion estimation (e.g. of a vehicle) from visual inputs of a stereo pair of video cameras are described. 3D egomotion estimation is a six degrees of freedom problem in general. In embodiments of the present invention, this is simplified to four dimensions and further decomposed to two two-dimensional sub-solutions. The decomposition allows use of a voting strategy that identifies the most probable solution. An input is a set of image correspondences between two temporally consecutive stereo pairs, i.e. feature points do not need to be tracked over time. The experiments show that even if a trajectory is put together as a simple concatenation of frame-to-frame increments, the results are reliable and precise.Type: GrantFiled: May 31, 2011Date of Patent: June 3, 2014Assignees: Toyota Motor Europe NV/SA, Czech Technical University in PragueInventors: Gabriel Othmezouri, Ichiro Sakata, Jiri Matas, {hacek over (S)}t{hacek over (e)}pán Obdr{hacek over (z)}álek

Patent number: 8533139Abstract: Approaches for optimizing computation of minimum cut or maximum flow on graphs comprising a plurality of nodes and edges with grid-like topologies are disclosed. Embodiments exploit the regular structure of input graphs to reduce the memory bandwidth—a main bottleneck of popular max-flow/min-cut algorithms based on finding augmenting paths on a residual graph (such as Ford-Fulkerson [1956] or Boykov-Kolmogorov [2004]). Disclosed embodiments allow more than 200% speed-up without sacrificing optimality of the final solution, which is crucial for many computer vision and graphics applications. Method and system embodiments replace standard linked list representation of general graphs with a set of compact data structures with blocked memory layout that enables fixed ordering of edges and implicit branchless addressing of nodes.Type: GrantFiled: September 6, 2011Date of Patent: September 10, 2013Assignee: Czech Technical University in Prague, Faculty of Electrical EngineeringInventors: Ond{hacek over (r)}ej Jamri{hacek over (s)}ka, Daniel Sýkora
