摘要： This disclosure describes selective deblock filtering techniques that are particularly useful with coding standards that do not specify in-loop deblock filtering for standard compliance. In accordance with this disclosure, deblock filtering may be selectively performed with respect to block boundaries of a given video block being coded, a motion compensation process can be performed using a filtered version of the prediction video frame used to code the given video block, or both. This disclosure also provides selection rules that can be applied to determine what type of deblocking techniques to apply in various scenarios. The selection rules may improve the video coding and may also ensure that mismatch between video blocks at an encoder and a decoder is not introduced by the deblock filtering.

摘要： This disclosure describes techniques for processing motion vectors such that the resulting motion vectors better correlate with the true motion of a video frame. In one example, the techniques may include comparing a block motion vector corresponding to a video block to a sub-block motion vector corresponding to a sub-block contained within the video block. The techniques may further include selecting one of the block motion vector and the sub-block motion vector as a spatially-estimated motion vector for the sub-block based on the comparison. Motion vectors that better correlate with true motion may be useful in applications such as motion compensated frame interpolation (MCI), moving object tracking, error concealment, or other video post-processing that requires the true motion information.

摘要： This disclosure describes techniques for region-of-interest (ROI) encoding. In accordance with the techniques described herein, an encoding device may determine a temporal spatial dependency value for a candidate reference video block for inter-coding a current block in a video frame. The encoding device may compare the temporal spatial dependency value to a threshold value and select a coding mode for the current block based on the comparison. A decoding device may receive data defining a ROI as well as the temporal spatial dependency value and decode a video block in the ROI based at least in part on the temporal spatial dependency value. In this manner, the techniques of this disclosure may allow a video content viewer the ability to choose a ROI to watch.

摘要： This disclosure describes techniques for performing content adaptive histogram enhancement. In accordance with the content adaptive histogram enhancement techniques of this disclosure, a frame of digital image data, e.g., digital video data or digital still image data, is classified into one of a plurality of content classes based on histogram of pixel intensity values of the frame. The content classes may represent various levels of brightness, contrast, or the like. To classify the frame into the corresponding content class, a shape of the histogram may be analyzed using various histogram statistics. Based on the content class of the frame, the pixel intensity values of the frame are mapped to new pixel intensity values.

摘要： A video decoder performs a sequential error handling process to detect and conceal errors within a corrupted data segment of video data units. The decoder sequentially decodes a current data unit. Upon detecting an error, the decoder sets an error flag and resynchronizes decoding at the start of the next unit. If the error flag is set, the video decoder identifies the end of the corrupted data segment based on the start of the later unit. The decoder conceals data between the start of the current unit and the end of the corrupted data segment. If the error flag is not set, the decoder may decode the remainder of the current unit and proceed to decode the next available unit without performing error handling and concealment for the current unit. The decoder also may address reference unit mismatches caused by lost video data units.

摘要： In general, the disclosure describes various techniques for providing edge-directed scaling filters that may be used to scale image data. An example device includes a storage medium configured to store a first lookup table and a second lookup table, and one or more processors configured to obtain one or more gradient values that each indicates a gradient between values of at least two pixels in a source image. The one or more processors are also configured to generate one or more inverse gradient values from a first lookup table based on the gradient values, and to generate one or more edge-directed scaling filter coefficients from a second lookup table based on the inverse gradient values. The one or more processors may be further configured to generate an edge-directed filter based on the coefficients, and to apply the filter to the at least two pixels to generate an interpolated pixel.

摘要： This disclosure provides intelligent frame skipping techniques that may be used by an encoding device or a decoding device to facilitate frame skipping in a manner that may help to minimize quality degradation due to the frame skipping. In particular, the described techniques may implement a similarity metric designed to identify good candidate frames for frame skipping. In this manner, noticeable reductions in the video quality caused by frame skipping, as perceived by a viewer of the video sequence, may be reduced relative to conventional frame skipping techniques. The described techniques advantageously operate in a compressed domain.
