Abstract: A vehicular vision system includes a camera disposed at a body portion of a vehicle and having a field of view exterior of the vehicle. The camera has an imager and a fisheye lens with more distortion at side regions of the field of view than at a center region of the field of view. An electronic control unit (ECU), via image processing of captured image data, determines gradient information and determines edges of intensity gradients present at a side region of the field of view of the camera. The system, based at least in part on determined edges of intensity gradients, determines a potential cross traffic object at the side region and determines movement of upper and lower portions of a determined edge of an intensity gradient of the cross traffic object to determine if the cross traffic object is moving into a path of the vehicle.

Each sub-pattern is adjacent to at least one other sub-pattern, and each sub-pattern is different from each other sub-pattern. Each sub-pattern includes a first number of portions in a sub-row and a second number of portions in a sub-column. Each sub-row extends in the first direction and each sub-column extends in a second direction that is substantially orthogonal to the first direction. Each portion may be a first-type portion or a second-type portion. A size of a first-type portion is larger in the first direction and in the second direction than a size of a second-type portion in the first direction and in the second direction. In one embodiment, a first-type portion is a black portion and the second-type portion is a white portion.

Abstract: Video processing methods and apparatuses in a video encoding or decoding system for processing residual data of transform blocks. A current transform block in a video picture is divided into multiple sub-blocks, and each sub-block in the current transform block is entropy encoded or decoded using multiple sub-block coding passes. Each transform coefficient level in each sub-block is visited once according to a pre-defined scanning order in each sub-block coding pass. Two or more syntax elements associated with transform coefficient levels in the current transform block are aggregated and coded in one single sub-block coding pass. The video processing method is applied if the current transform block contains at least one non-zero transform coefficient level and the current transform block is coded in Transform Skip Mode (TSM) according to some embodiments.

Abstract: Particular embodiments provide a variable, BitDepth, that may be set at a value based on a number of bits used to represent pixels in pictures of a video. The variable may be used in syntax elements in HEVC, such as the HEVC range extension, but other coding standards may be used. By using the variable, different resolutions for the video may be accommodated during the encoding and decoding process. For example, the number of pixels in the pictures may be represented by 8 bits, 10 bits, 12 bits, or another number of bits depending on the resolution. Using the BitDepth variable in the syntax provides flexibility in the motion estimation and motion compensation process. For example, syntax elements used in the weighted prediction process may take into account different numbers of bits used to represent the pictures.

The one or more given scenes of the video content of the given type and given one of the titles can be encoded using corresponding scenes specific encoding parameter values, and the non-given scenes can be encoded using one or more general encoding parameter values. The one or more given titles can be selected based on a rate of streaming of various video content titles of the given type.

Abstract: The feel of brightness intended by a production side is satisfactorily reproduced on a reception side. Transmission video data is acquired by applying a predetermined opto-electrical transfer function to input video data. The transmission video data is transmitted along with region information indicating a region in which a brightness conversion is allowed. A transmission unit for example transmits a video stream acquired by encoding the transmission video data, and the region information is inserted into a layer of the video stream. On the reception side, an electro-optical transfer function corresponding to the predetermined opto-electrical transfer function is applied to the transmission video data, and display video data is acquired by performing brightness conversion processing on the basis of the region information.
