Patent number: 9569694Abstract: An image processor (10) has a window selector for choosing a detection window within the image, and a self similarity computation part (40) for determining self-similarity information for a group of the pixels in any part of the detection window, to represent an amount of self-similarity of that group to other groups in any other part of the detector window, and for repeating the determination for groups in all parts of the detection window, to generate a global self similarity descriptor for the detection window. A classifier (50) is used for classifying whether an object is present based on the global self-similarity descriptor. By using global self-similarity rather than local similarities more information is captured which can lead to better classification. In particular, it helps enable recognition of more distant self-similarities inherent in the object, and self-similarities present at any scale.Type: GrantFiled: January 6, 2016Date of Patent: February 14, 2017Assignees: TOYOTA MOTOR EUROPE NV/SA, TECHNISCHE UNIVERSITAT DARMSTADTInventors: Gabriel Othmezouri, Ichiro Sakata, Bernt Schiele, Stefan Walk, Nikodem Majer, Konrad Schindler

Patent number: 8958600Abstract: Methods and apparatus are described for monocular 3D human pose estimation and tracking, which are able to recover poses of people in realistic street conditions captured using a monocular, potentially moving camera. Embodiments of the present invention provide a three-stage process involving estimating (10, 60, 110) a 3D pose of each of the multiple objects using an output of 2D tracking-by detection (50) and 2D viewpoint estimation (46). The present invention provides a sound Bayesian formulation to address the above problems. The present invention can provide articulated 3D tracking in realistic street conditions. The present invention provides methods and apparatus for people detection and 2D pose estimation combined with a dynamic motion prior. The present invention provides not only 2D pose estimation for people in side views, it goes beyond this by estimating poses in 3D from multiple viewpoints. The estimation of poses is done in monocular images, and does not require stereo images.Type: GrantFiled: June 14, 2011Date of Patent: February 17, 2015Assignees: Toyota Motor Europe NV/SA, Technische Universitat DarmstadtInventors: Gabriel Othmezouri, Ichiro Sakata, Bernt Schiele, Mykhaylo Andriluka, Stefan Roth

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
