Publication number: 20160092473Abstract: A privacy-preserving multi-query parking management system and method. An image of a vehicle with respect to a specific part (e.g., license plate) can be captured when the vehicle enters via an entry point. An image signature can be computed by embedding the image into a descriptor space and the image signature can be stored in a database together with relevant metadata. An image of a vehicle with respect to the specific part can be captured when the vehicle exits via at least one exit point and an image signature can be computed. An entry-exit association with respect to the vehicle can be performed by searching for a most similar image signature in the database. Additionally, given a textual query (e.g., a license plate number), a signature can be computed by embedding the text into the same descriptor space.Type: ApplicationFiled: September 26, 2014Publication date: March 31, 2016Inventors: Jose Antonio Rodriguez-Serrano, Florent Perronnin

Patent number: 9158995Abstract: A computer implemented method for localization of an object, such as a license plate, in an input image includes generating a task-dependent representation of the input image based on relevance scores for the object to be localized. The relevance scores are output by a classifier for a plurality of locations in the input image, such as patches. The classifier is trained on patches extracted from training images and their respective relevance labels. One or more similar images are identified from a set of images, based on a comparison of the task-dependent representation of the input image and task-dependent representations of images in the set of images. A location of the object in the input image is identified based on object location annotations for the similar images.Type: GrantFiled: March 14, 2013Date of Patent: October 13, 2015Assignee: XEROX CORPORATIONInventors: Jose Antonio Rodriguez-Serrano, Diane Larlus-Larrondo

Patent number: 9158971Abstract: A system and method enable generating a specific object detector for a category of interest. The method includes identifying seed objects in frames of a video sequence with a pre-trained generic detector for the category. An appearance model is iteratively learned for each of the seed objects using other frames in which the seed object is identified. The appearance models are learned jointly to optimize a loss function which accounts for the loss of incorrectly labeling sub-images and a regularization term which measures a distance between the appearance models. The loss of incorrectly labeling sub-images is determined using a motion model which predicts the location of the seed object in the subsequent frames so that sub-images outside the location that the current appearance model contribute to the loss. The specific object detector is then generated by aggregating the optimized appearance models.Type: GrantFiled: March 3, 2014Date of Patent: October 13, 2015Assignee: XEROX CORPORATIONInventors: Adrien Gaidon, Gloria Zen, José Antonio Rodriguez Serrano

Publication number: 20150278632Abstract: Methods and systems for detecting an object part location based on an extended date-driven detection. A specific relevance value between configurations of parts with respect to a set of training images annotated with annotating objects can be defined. A similarity learning algorithm can be applied with respect to the parts to obtain a similarity function based on the similarity between the part configurations. The similarity learning algorithm receives a set of positive pair having similar part configuration and a negative pair having different configuration and returns the similarity function that tends to assign a high score to new positive pair and a low score to negative pairs. A similarity between a new image and the training images can be measured utilizing the learned similarity function to obtain a neighbor image and a visible and/or non-visible part location with respect to the image can be predicted based on the neighbor image.Type: ApplicationFiled: March 28, 2014Publication date: October 1, 2015Applicant: Xerox CorporationInventors: Jose-Antonio Rodriguez-Serrano, Zhenwen Dai

Patent number: 9098749Abstract: Methods, systems, and processor-readable media for pruning a training dictionary for use in detecting anomalous events from surveillance video. Training samples can be received, which correspond to normal events. A dictionary can then be constructed, which includes two or more classes of normal events from the training samples. Sparse codes are then generated for selected training samples with respect to the dictionary derived from the two or more classes of normal events. The size of the dictionary can then be reduced by removing redundant dictionary columns from the dictionary via analysis of the sparse codes. The dictionary is then optimized to yield a low reconstruction error and a high-interclass discriminability.Type: GrantFiled: March 14, 2013Date of Patent: August 4, 2015Assignee: Xerox CorporationInventors: Raja Bala, Zhigang Fan, Aaron Michael Burry, Jose Antonio Rodriguez-Serrano, Vishal Monga, Xuan Mo

Patent number: 9075824Abstract: An instance-level retrieval method and system are provided. A representation of a query image is embedded in a multi-dimensional space using a learned projection. The projection is learned using category-labeled training data to optimize a classification rate on the training data. The joint learning of the projection and the classifiers improves the computation of similarity/distance between images by embedding them in a subspace where the similarity computation outputs more accurate results. An input query image can thus be used to retrieve similar instances in a database by computing the comparison measure in the embedding space.Type: GrantFiled: April 27, 2012Date of Patent: July 7, 2015Assignee: XEROX CORPORATIONInventors: Albert Gordo, Jose Antonio Rodriguez Serrano, Florent Perronnin

Publication number: 20150104073Abstract: A method for recognition of an identifier such as a license plate includes storing first visual signatures, each extracted from a first image of a respective object, such as a vehicle, captured at a first location, and first information associated with the first captured image, such as a time stamp. A second visual signature is extracted from a second image of a second object captured at a second location and second information associated with the second captured image is acquired. A measure of similarity is computed between the second visual signature and at least some of the first visual signatures to identify a matching one. A test is performed, which is a function of the first and the second information associated with the matching signatures. Only when it is confirmed that the test has been met, identifier recognition is performed to identify the identifier of the second object.Type: ApplicationFiled: October 16, 2013Publication date: April 16, 2015Applicant: Xerox CorporationInventors: Jose Antonio Rodriguez-Serrano, Florent C.

Publication number: 20150046119Abstract: Methods, systems and processor-readable media for vehicle classification. In general, one or more vehicles can be scanned utilizing a laser scanner to compile data indicative of an optical profile of the vehicle(s). The optical profile associated with the vehicle(s) is then pre-processed. Particular features are extracted from the optical profile following pre-processing of the optical profile. The vehicle(s) can be then classified based on the particular features extracted from the optical feature. A segmented laser profile is treated as an image and profile features that integrate the signal in one of the two directions of the image and Fisher vectors which aggregate statistics of local “patches” of the image are computed and utilized as part of the extraction and classification process.Type: ApplicationFiled: August 9, 2013Publication date: February 12, 2015Applicant: Xerox CorporationInventors: Harsimrat Singh Sandhawalia, Jose Antonio Rodriguez Serrano, Herve Poirier, Gabriela Csurka
