Abstract: In general, techniques are described for performing residual prediction in video coding. As one example, a device configured to code scalable or multi-view video data may comprise one or more processors configured to perform the techniques. The processors may determine a difference picture, for a current picture, based on a first reference picture in a same layer or view as the current picture and a decoded picture in a different layer or view as the current picture. The decoded picture may be in a same access unit as the first reference picture. The processors may perform bi-prediction based on the difference picture to code at least a portion of the current picture.

Abstract: A method of optimizing an encoded video stream comprising one or more video frames, each video frame comprising a plurality of macroblocks, each macroblock comprising a plurality of pixels. The method includes receiving an encoded macroblock, decoding the encoded macroblock, and extracting a first quantization parameter. The first quantization parameter corresponds to quantization settings originally used for compressing the encoded macroblock. The method also includes computing a second quantization parameter based at least in part on the first quantization parameter, re-encoding the decoded macroblock based on the second quantization parameter, and providing the re-encoded macroblock.

Abstract: The invention relates to a method and a device for improving the depth impression of stereoscopic images and image sequences. In autostereoscopic multi-viewer display devices, generally a plurality of intermediate perspectives are generated, which lead to a reduced stereo base upon perception by the viewers. The stereo base widening presented in this application leads to a significant improvement and thus to a more realistic depth impression. It can either be effected during recording in the camera or be integrated into a display device. The improvement in the depth impression is achieved by the generation of synthetic perspectives situated, in the viewing direction of the camera lenses, on the left and right of the extreme left and extreme right recorded camera perspective on the right and left lengthening of the connection line formed by the extreme left and extreme right camera perspectives.

Abstract: An image processing apparatus includes a coordinate conversion unit and a drawing unit. The coordinate conversion unit obtains a coordinate of an intersection PVG between a stereoscopic projection plane and a line connecting a ground point PRG of a stereoscopic object and a virtual viewpoint position VP, and a coordinate of an intersection PV between a line extending upward from the intersection PVG and a line connecting a point PR of the stereoscopic object and the virtual viewpoint position VP. The drawing unit projects an image of the ground point PRG of the stereoscopic object at the position of the coordinate of PVG, and projects the image of PR of the stereoscopic object at the position of PV.

Abstract: Techniques are provided to implement line based processing of thermal images and a flexible memory system. In one example, individual lines of a thermal image frame may be provided to an image processing pipeline. Image processing operations may be performed on the individual lines in stages of the image processing pipeline. A memory system may be used to buffer the individual lines in the pipeline stages. In another example, a memory system may be used to send and receive data between various components without relying on a single shared bus. Data transfers may be performed between different components and different memories of the memory system using a switch fabric to route data over different buses. In another example, a memory system may support data transfers using different clocks of various components, without requiring the components and the memory system to all be synchronized to the same clock source.

Abstract: A video coder can determine a most probable mode for a block of video data using non-square partitions based on the direction of the non-square partitions. When the direction of the non-square partitions is vertical, an intra prediction mode of a left-neighboring block can be selected as the most probable intra prediction mode, and when the direction of the non-square partitions is horizontal, an intra prediction mode of an above-neighboring block can be selected as the most probable intra prediction mode.

Abstract: A user activation of an image capture function of a mobile device is received. The image capture function is for a surround image mode. Two or more camera lenses are approximately concurrently activated. A front-side image from a first camera lens and a rear-side image from a second camera lens can be optically captured. A second front-side image from the first camera lens and a second rear-side image from the second camera lens can be optically captured responsive to a manual pan/tilt/zoom operation of the front-side or rear-side lense. Content from the front-side images and content from the rear-side images are recorded in a non-transitory storage medium of the mobile device within a single file for a surround mode image.

Abstract: Video monitoring and alarm verification technology, in which a first connection is established between a first device and a camera located in a monitored property associated with a user of the first device and image data captured by the camera is received over the first connection and at the first device. A determination is made to establish a second connection with a second device that enables sharing of the received image data with the second device and, in response to the determination, the second connection is established between the first device and the second device. The received image data is shared with the second device over the second connection and the second device is restricted from directly accessing image data captured by the camera located in the monitored property.

Abstract: The video encoders described herein may make an initial determination to designate a macroblock as a skip macroblock, but may subsequently reverse that decision based on additional information. For example, an initial skip mode decision may be based on aggregate distortion metrics for the luma component of the macroblock (e.g., SAD, SATD, or SSD), then reversed based on an individual pixel difference metric, an aggregate or individual pixel metric for a chroma component of the macroblock, or on the position of the macroblock within a macroblock row. The final skip mode decision may be based, at least in part, on the maximum difference between any pixel in the macroblock (or in a region of interest within the macroblock) and the corresponding pixel in a reference frame. The initial skip mode decision may be made during an early stage of a pipelined video encoding process and reversed in a later stage.
