Publication number: 20210365735Abstract: A computer-implemented method for training a classifier (??), including: training a pretext model (??) to learn a pretext task, so as to minimize a distance between an output of a source sample via the pretext model (??) and an output of a corresponding transformed sample via the pretext model (??), the transformed sample being a sample obtained by applying a transformation (T) to the source sample; S20) determining a neighborhood (NXi) of samples (Xi) of a dataset (SD) in the embedding space; S30) training the classifier (??) to predict respective estimated probabilities ??j(Xi), j=1 . . . C, for a sample (Xi) to belong to respective clusters (Cj), by using a second training criterion which tends to: maximize a likelihood for a sample and its neighbors (Xj) of its neighborhood (Nxi) to belong to the same cluster; and force the samples to be distributed over several clusters.Type: ApplicationFiled: May 21, 2021Publication date: November 25, 2021Applicants: Toyota Jidosha Kabushiki Kaisha, Katholieke Universiteit LeuvenInventors: Wim Abbeloos, Gabriel Othmezouri, Wouter Van Gansbeke, Simon Vandenhende, Marc Proesmans, Stamatios Georgoulis, Luc Van Gool

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
