Patent number: 9800898Abstract: Syntax structures that indicate the completion of coded regions of pictures are described. For example, a syntax structure in an elementary bitstream indicates the completion of a coded region of a picture. The syntax structure can be a type of network abstraction layer unit, a type of supplemental enhancement information message or another syntax structure. For example, a media processing tool such as an encoder can detect completion of a coded region of a picture, then output, in a predefined order in an elementary bitstream, syntax structure(s) that contain the coded region as well as a different syntax structure that indicates the completion of the coded region. Another media processing tool such as a decoder can receive, in a predefined order in an elementary bitstream, syntax structure(s) that contain a coded region of a picture as well as a different syntax structure that indicates the completion of the coded region.Type: GrantFiled: May 6, 2015Date of Patent: October 24, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Yongjun Wu, Lihua Zhu, Shyam Sadhwani, Gary J.

Patent number: 9774845Abstract: A system that incorporates teachings of the present disclosure may include, for example, controller and a memory that stores executable instructions that, when executed by the controller, facilitate performance of operations that include receiving a media content including three-dimensional image content for presentation on a display device. A presence is determined of a viewer within a line-of-sight of the display device, wherein the viewer is without a viewing apparatus that facilitates viewing of the three-dimensional image content. The media content is adapted to include two-dimensional image content, based on the determining of the presence of the viewer within the line-of-sight and without the viewing apparatus. Other embodiments are disclosed.Type: GrantFiled: May 26, 2016Date of Patent: September 26, 2017Assignee: AT&T Intellectual Property I, L.P.Inventors: Robert King, Sharon E. Carter

Patent number: 9762927Abstract: Techniques are described for sub-prediction unit (PU) based motion prediction for video coding in HEVC and 3D-HEVC. In one example, the techniques include an advanced temporal motion vector prediction (TMVP) mode to predict sub-PUs of a PU in single layer coding for which motion vector refinement may be allowed. The advanced TMVP mode includes determining motion vectors for the PU in at least two stages to derive motion information for the PU that includes different motion vectors and reference indices for each of the sub-PUs of the PU. In another example, the techniques include storing separate motion information derived for each sub-PU of a current PU predicted using a sub-PU backward view synthesis prediction (BVSP) mode even after motion compensation is performed. The additional motion information stored for the current PU may be used to predict subsequent PUs for which the current PU is a neighboring block.Type: GrantFiled: September 25, 2014Date of Patent: September 12, 2017Assignee: QUALCOMM IncorporatedInventors: Ying Chen, Li Zhang

Patent number: 9760768Abstract: A spherical content capture system captures spherical video content. A spherical video sharing platform enables users to share the captured spherical content and enables users to access spherical content shared by other users. In one embodiment, captured metadata or video/audio processing is used to identify content relevant to a particular user based on time and location information. The platform can then generate an output video from one or more shared spherical content files relevant to the user. The output video may include a non-spherical reduced field of view such as those commonly associated with conventional camera systems. Particularly, relevant sub-frames having a reduced field of view may be extracted from each frame of spherical video to generate an output video that tracks a particular individual or object of interest.Type: GrantFiled: March 3, 2015Date of Patent: September 12, 2017Assignee: GoPro, Inc.Inventors: Timothy MacMillan, David A.

Patent number: 9747499Abstract: Described are systems and methods for recognizing paper documents on a tabletop using an overhead camera mounted on pan-tilt servos. The described automated system first finds paper documents on a cluttered desk based on a text probability map, constructed using multiple images acquired at fixed grid positions, and then captures a sequence of high-resolution overlapping frames of the located document(s), which are then fused together and perspective-rectified, using computed homography, to reconstruct a high quality and fronto-parallel document image that is of sufficient quality required for optical character recognition. The extracted textual information may be used, for example, for indexing and search, document repository and/or language translation applications.Type: GrantFiled: March 3, 2015Date of Patent: August 29, 2017Assignee: FUJI XEROX CO., LTD.Inventors: Chelhwon Kim, Patrick Chiu, Hao Tang

Patent number: 9712848Abstract: Each set of pels of an image frame is encoded into a corresponding set of codewords having fixed-length and unary variable-length components. The variable-length components are combined into a variable-length portion and the fixed-length components are separately combined into a fixed-length portion that is attached to the variable-length portion to complete a bit segment. For decompression, a first bit string of a fixed number of bits is identified as a fixed-length portion of the bit segment. A search window placed adjacent to the first bit string is scanned to find a second bit string having a number of termination bits equal to the number of codewords in the set, with the second bit string thus representing the variable-length portion of a corresponding bit segment. Each variable-length component of the identified variable-length portion is combined with a corresponding fixed-length component of the identified fixed-length portion to recreate a corresponding codeword.Type: GrantFiled: November 10, 2014Date of Patent: July 18, 2017Assignee: VIXS SYSTEMS INC.Inventors: Wendy Wai Yin Cheung, Xin Guo

Patent number: 9703939Abstract: A mobile terminal having a face recognition function and a control method thereof are provided. A mobile terminal includes a display unit, a memory, a photographing unit and a controller. The memory stores first photographing distance information mapped to a plurality of coordinates in a previously obtained first face image, as reference information for releasing a lock mode in which a touch input applied to the display unit is restricted. The photographing unit obtains a second face image by photographing a subject, when a face recognition function is performed in the lock mode. The controller computes second photographing distance information mapped to the plurality of coordinates in the second face image, and releases the lock mode, based on a result obtained by comparing the first photographing distance information and the second photographing distance information.Type: GrantFiled: May 22, 2013Date of Patent: July 11, 2017Assignee: LG ELECTRONICS INC.Inventors: Uisoo Tahk, Minhun Ha, Uijun Kim, Jaeyee Lee, Sanghoon Kim

Patent number: 9681139Abstract: A video/image compression method based on an region of interest (ROI) can be performed in a variable block video encoder such as a HEVC. A ROI coding method using variable block size coding information partitions a maximum coding unit (LCU) block obtained from an image into coding unit (CU) blocks. To obtain a quantization parameter of each coding unit (CU) block, the value of its quantization parameter is assigned based on its first hierarchical depth information and its second hierarchical depth information by using the first hierarchical depth information related to the size of the coding unit (CU) block and using the second hierarchical depth information related to the size of a prediction unit (PU) block correspondingly represented in consequence of the partition of the coding unit (CU) block. The resulting values of a quantization parameter assigned to different coding unit (CU) blocks may be different.Type: GrantFiled: March 5, 2014Date of Patent: June 13, 2017Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Nyeong-Kyu Kwon, Insu Park
