Patent number: 8891009Abstract: A system and method for retargeting video sequences are provided. A method for retargeting a video includes a plurality of frames includes determining saliency information for the plurality of frames, determining a cost metric for the video, and retargeting the video based on the cost metric to produce a retargeted video. The cost metric considers loss due to cropping, scaling, temporal factors, and spatial factors. The retargeting makes use of a crop window for each frame in the plurality of frames.Type: GrantFiled: August 29, 2011Date of Patent: November 18, 2014Assignee: Futurewei Technologies, Inc.Inventors: Taoran Lu, Zheng Yuan, Yu Huang, Dapeng Oliver Wu, Hong Heather Yu

Patent number: 8483427Abstract: In accordance with an embodiment, a method of authenticating images includes electronically receiving an anchor image and a query image, performing a feature point extraction of an anchor image, and performing a feature point extraction of a query image. The method also includes clustering feature points of the anchor image and feature points of the query image, where clustering includes determining matching feature points, determining outlier feature points, and excluding outlier feature points. Whether the anchor image is similar to the query image is determined based on a distance between the feature points of the anchor image and the feature points of the query image. If the anchor image is similar to the query image, possible tampered areas of the query image based on the outlier feature points are identified.Type: GrantFiled: September 28, 2010Date of Patent: July 9, 2013Assignee: Futurewei Technologies, Inc.Inventors: Lei Yang, Jun Tian, Dapeng Oliver Wu, Hong Heather Yu

Patent number: 8406297Abstract: A system and method for region-of-interest-based bit-allocation scheme for video coding is provided. A method for encoding an image sequence of inter-frames and intra-frames includes grouping the inter-frames and the intra-frames in at least one group of pictures (GOP), and performing a frame-level bit-allocation to inter-frames and the intra-frames in the GOP. For each frame of the inter-frames and the intra-frames in the GOP, the method also includes partitioning the frame into a plurality of macroblocks, identifying macroblocks in the plurality of macroblocks as having regions of interest (ROI), and performing a macroblock level bit-allocation for the frame based on macroblocks identified as having ROI. The method further includes encoding the image sequence based on the bit-allocations, thereby producing an encoded image sequence, and outputting the encoded image sequence.Type: GrantFiled: September 3, 2009Date of Patent: March 26, 2013Assignee: FutureWei Technologies, Inc.Inventors: Taoran Lu, Zhifeng Chen, Dapeng Oliver Wu, Yu Huang, Jun Tian, Hong Heather Yu
