Abstract: Security guards at big facilities, such as airports, monitor multiple screens that display images from individual surveillance cameras dispersed throughout the facility. If a guard zooms with a particular camera, he will lose image resolution, along with perspective on the surrounding area. Embodiments of the inventive Imaging System for Immersive Surveillance (ISIS) solve these problems by combining multiple cameras in one device. When properly mounted, example ISIS systems offer 360-degree, 100-megapixel views on a single screen. (Other resolutions may also be employed.) Image-stitching software merges multiple video feeds into one scene. The system also allows operators to tag and follow targets, and can monitor restricted areas and sound an alert when intruders breach them.

Abstract: A method of decoding JVET video includes receiving a bitstream and calculating a final planar prediction in planar mode to predict pixel values for a current coding block. The final planar prediction may rely on using unequal weights applied to each of a horizontal and vertical predictor, where such predictors may be generated by interpolating neighboring pixels for each predicted pixel within a coding block. The computation may be made more accurate by deriving a value for a bottom right neighboring pixel.

Abstract: A display control device is installed in a vehicle and causes to display a video of an area around the vehicle from an imaging device to be displayed on a display device. An acquirer acquires a first video serving as a processing target from the imaging device. A receiver receives an instruction to move an extraction range for extracting at least a part of the first video acquired by the acquirer. An output unit outputs a second video extracted in the extraction range moved in accordance with the instruction received by the receiver to the display device. When the extraction range moved in accordance with the instruction received by the receiver reaches an end portion of the first video, the output unit gives a notification indicating the reaching.

Abstract: A multi-view interactive digital media representation (MVIDMR) of an object can be generated from live images of an object captured from a camera. Selectable tags can be placed at locations on the object in the MVIDMR. When the selectable tags are selected, media content can be output which shows details of the object at location where the selectable tag is placed. A machine learning algorithm can be used to automatically recognize landmarks on the object in the frames of the MVIDMR and a structure from motion calculation can be used to determine 3-D positions associated with the landmarks. A 3-D skeleton associated with the object can be assembled from the 3-D positions and projected into the frames associated with the MVIDMR. The 3-D skeleton can be used to determine the selectable tag locations in the frames of the MVIDMR of the object.

Abstract: A method of decoding JVET video, comprising receiving a bitstream indicating how a coding tree unit was partitioned into coding units according to a partitioning structure that allows nodes to be split according to a partitioning technique. An intra direction mode for a coding unit may be selected, as well as one or more of the plurality of reference lines to generate at least one predictor for the intra direction mode. A predictor may be generated from reference samples within each selected reference line by combining predicted pixel values based on a projected position on a main reference line in combination with predicted pixel values based on a projected position on a side reference line. The predicted pixel values are weighted according to a weight parameter, wherein the weight parameter is determined based on a shift conversion factor.

Abstract: Various implementations provide one or more of improved programming channel change time and/or overall quality of television reception by using multiple transmission channels. In one particular implementation, a first layer of a picture is encoded using a first level of error protection. The encoded first layer has a first decoding delay. A second layer of the picture is encoded using a second level of error protection. The encoded second layer has a second decoding delay. The second level of error protection is lower than the first level of error protection, and the second decoding delay is longer than the first decoding delay. Other implementations provide a signal or signal structure carrying the encoded first and second layers. Yet further implementations decode the encoded first and second layers.

Abstract: Because human eyes may become less sensitive to dark areas around very bright areas in a video (known as glare masking), we may use coarser quantization in such dark areas. Considering the extra distortion that human eyes can tolerate in a block with glare masking, a quantization ratio for the block can be calculated. The quantization parameter for the block can then be scaled up using the quantization ratio to form an adjusted quantization parameter. In one embodiment, the adjusted quantization parameter can be derived at the decoder side, and thus, transmission of quantization ratio information is not needed. In particular, we can estimate the luminance of a current block based on a predicted block and de-quantized DC coefficient, and use the luminance of causal neighboring blocks and the estimated luminance of the current block to estimate the adjusted quantization parameter.

Abstract: Approaches for transcoding on-the-fly (TOTF). A digital video is encoded to produce a set of encoding decisions. A video quality profile is created that describes the set of encoding decisions. Upon determining that the video quality profile is associated with a compressed digital video bit stream, a final rate of compression is determined, frame by frame, for the compressed digital video bit stream using the video quality profile. The final rate of compression may be determined either internal or external to an encoder/transcoder. The video quality profile may be created by reviewing a plurality of encoding decisions to determine which encoding decisions merit inclusion based on a variety of criteria.
