Patent number: 8854060Abstract: A physiological measurement instrument is disclosed, having a detector, implemented as one or more sensors, for measuring values of one or more physiological measured parameters associated with a body of a human or animal subject, and for detecting values of a physical parameter that indicates an operating position of the measurement instrument relative to the body, and an operating-position-determining unit that receives and analyzes output signals from the detector, to determine the operating position of the measurement instrument.Type: GrantFiled: November 1, 2010Date of Patent: October 7, 2014Assignee: BIOTRONIK CRIM Patent AGInventors: Michael Diebold, Jens Philipp, Thomas Finnberg

Patent number: 8831760Abstract: A method for performing audio copy detection, comprising, providing a query audio data, the query audio data having a succession of frames and also providing a plurality of test audio data units, each test audio data unit including a succession of frames. For each test audio data unit the method generates a test fingerprint set. The generation of the test fingerprint test including computing similarity measurements between at least one frame of the test audio data and a plurality of frames of the query audio data. A test audio data unit is then selected as a match for the query audio data at least in part on the basis of the fingerprint sets.Type: GrantFiled: October 1, 2010Date of Patent: September 9, 2014Assignee: (CRIM) Centre de Recherche Informatique de MontrealInventors: Vishwa Gupta, Gilles Boulianne, Patrick Cardnal

Patent number: 8760575Abstract: The computer readable storage medium includes computer executable instructions for implementing a videodescription player module. The computer executable instructions implementing a user interface for selecting one or more videodescription output options among a plurality of videodescription output options. A videodescription player module generates a videodescription output that includes vocal communication information according to the selected output option.Type: GrantFiled: September 2, 2011Date of Patent: June 24, 2014Assignee: Centre de Recherche Informatique de Montreal (Crim)Inventors: Langis Gagnon, Claude Chapdelaine, David Byrns

Patent number: 8671109Abstract: A method to detect video copying based on content. The method comprises providing a set of reference data elements derived from a set of reference video frames in a reference video stream; providing a set of query data elements derived from a set of query video frames in a query video stream, each of the query data elements having a corresponding query data element identifier; associating with each of the reference data elements a fingerprint selected from among the query data element identifiers; and determining a similarity measure for the query video stream relative to the reference video stream by a comparison of the query data element identifiers to the fingerprints.Type: GrantFiled: December 2, 2011Date of Patent: March 11, 2014Assignee: CRIM (Centre de Recherche Informatique de Montreal)Inventors: Vishwa N. Gupta, Parisa Darvish Zadeh Varcheie

Patent number: 8423363Abstract: Occurrences of one or more keywords in audio data are identified using a speech recognizer employing a language model to derive a transcript of the keywords. The transcript is converted into a phoneme sequence. The phonemes of the phoneme sequence are mapped to the audio data to derive a time-aligned phoneme sequence that is searched for occurrences of keyword phoneme sequences corresponding to the phonemes of the keywords. Searching includes computing a confusion matrix. The language model used by the speech recognizer is adapted to keywords by increasing the likelihoods of the keywords in the language model. For each potential occurrences keywords detected, a corresponding subset of the audio data may be played back to an operator to confirm whether the potential occurrences correspond to actual occurrences of the keywords.Type: GrantFiled: January 13, 2010Date of Patent: April 16, 2013Assignee: CRIM (Centre de Recherche Informatique de Montréal)Inventors: Vishwa Nath Gupta, Gilles Boulianne

Publication number: 20090273711Abstract: A method for determining a location of a caption in a video signal associated with a Region Of Interest (ROI), such as a face or text, or an area of high motion activity. The video signal is processed to generate ROI location information, the ROI location information conveying the position of the ROI in at least one video frame. The position where a caption can be located within one or more frames of the video signal is then determined on the basis of the ROI location information. This is done by identifying at least two possible positions for the caption in the frame such that the placement of the caption in either one of the two positions will not mask the ROI. A selection is then made among the at least two possible positions. The position picked is the one that would typically be the closest to the ROI such as to create a visual association between the caption and the ROI.Type: ApplicationFiled: January 27, 2009Publication date: November 5, 2009Applicant: Centre de Recherche Informatique de Montreal (CRIM)Inventors: Claude Chapdelaine, Mario Beaulieu, Langis Gagnon
