Abstract: Context adaptive binary arithmetic coding (CABAC) techniques are generally described. Aspects of the techniques are generally directed to inheritance-based context initialization. An example video coding device includes a memory configured to store video data, and one or more processors. The processor(s) are configured to initialize context information for a current slice of a current picture by inheriting context information of a previously-coded block of a previously-coded picture of the stored video data as initialized context information for the current slice of the current picture. The processor(s) are further configured to code data of the current slice using the initialized context information.

Abstract: Coding techniques for a video image compression system involve improving an image quality of a sequence of two or more bi-directionally predicted intermediate frames, where each of the frames includes multiple pixels. One method involves determining a brightness value of at least one pixel of each bi-directionally predicted intermediate frame in the sequence as an equal average of brightness values of pixels in non-bidirectionally predicted frames bracketing the sequence of bi-directionally predicted intermediate frames. The brightness values of the pixels in at least one of the non-bidirectionally predicted frames is converted from a non-linear representation.

Abstract: The present embodiments solve the problem of low-quality stored footage from video stream by storing copies of data packets at a local storage device of the A/V recording and communication device. The locally stored data is subsequently (e.g., after the live stream has terminated) uploaded to a remote storage device. If any data packets are lost during the upload process, those lost data packets can be re-sent from the local storage device to the remote storage device so that the complete recording can be stored at the remote storage device. The subsequent upload process may, in some embodiments, comprise a reliable data transfer protocol.

Abstract: A method is provided for encoding a digital video with a video encoder that allows intra prediction of mode selection. The method includes dividing pixels from each intra prediction block into four groups based on phases of the pixels, progressively narrowing down a list of intra prediction modes over a series of stages based on a comparison of a cost value for each intra prediction mode at that stage against a threshold value, tentatively assigning the remaining intra prediction with the lowest cost value after the final stage to the block, calculating a heterogeneity index for each group of contiguous intra prediction blocks based on the tentative intra prediction mode selected for each block after the final stage, and finalizing the tentative intra prediction mode for each block if the group has a heterogeneity index above a predetermined threshold value.

Abstract: A novel technique for performing video matting, which is built upon a proposed image matting algorithm that is fully automatic is disclosed. The disclosed methods utilize a PCA-based shape model as a prior for guiding the matting process, so that manual interactions required by most existing image matting methods are unnecessary. By applying the image matting algorithm to these foreground windows, on a per frame basis, a fully automated video matting process is attainable. The process of aligning the shape model with the object is simultaneously optimized based on a quadratic cost function.
