Patent number: 9723316Abstract: When an intra prediction parameter indicates a horizontal prediction process, an intra prediction unit adds a value proportional to a change in a horizontal direction of the luminance values of pixels adjacent to the top of each block, which is a unit for prediction process of a coding block, to the luminance value of a pixel adjacent to the left of the block to set a result of the addition as a predicted value of a prediction image, whereas when the intra prediction parameter indicates a vertical prediction process, the intra prediction unit adds a value proportional to a change in a vertical direction of the luminance values of pixels adjacent to the left of the block to the luminance value of the pixel adjacent to the top of the block to set the result of the addition as a predicted value of the prediction image.Type: GrantFiled: May 30, 2012Date of Patent: August 1, 2017Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Akira Minezawa, Kazuo Sugimoto, Shunichi Sekiguchi

Patent number: 9706221Abstract: Reference pictures received via a video signal are downscaled to a specified resolution by a video encoder/decoder. For each current picture being processed by the video encoder/decoder, the current picture is maintained at its original received resolution, but is divided into blocks. Each block is further divided into sub-blocks, and each sub-block is compared, for a set of specified positions, to a corresponding block of the downscaled reference image to generate a set of candidate motion vectors. The candidate motion vectors are scored according to how closely their corresponding sub-block matches the corresponding block of the reference picture at the corresponding position, and a motion vector for each block of the current image is selected based on the scores. The selected motion vectors are used to process (e.g. encode) the video signal.Type: GrantFiled: October 29, 2013Date of Patent: July 11, 2017Assignee: VIXS SYSTEMS INC.Inventors: Xinghai Li, Xin Guo

Patent number: 9609333Abstract: Methods and apparatus for parsing friendly and error resilient merge flag coding in video coding are provided.

Patent number: 9609281Abstract: Validation of asset movement can begin with the definition of a virtual tripwire for video cameras of a video surveillance system that monitor a defined area of interest through which RFID-identified assets are conveyed. The virtual tripwire can visually define a boundary within the view field of the video camera. The video camera can detect the movement of an asset through a virtual tripwire and an asset management system can be notified of the potential misdirection of the asset. The asset management system can obtain the asset's RFID data from a RFID handling system that monitors the area of interest. The validity of the detected movement can be determined using RFID data and an asset movement specification that defines pathing rules for assets and virtual tripwires. When the movement of the asset is determined to be invalid, a record of suspect movement data can be generated for the asset.Type: GrantFiled: September 29, 2010Date of Patent: March 28, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventor: Pandian Mariadoss
