摘要： Implementations include video image processing systems, methods, and apparatus for downscaling video data using a phase control multi-tap downscale filter. For example, a device configured to process video information may include a memory configured to store a downscaling filter comprising a number of coefficients. A processor may be configured to receive video input data and determine a scale factor between the video input data and a video output. In addition, the processor may be configured to modify the downscaling filter based on the scale factor and the number of coefficients in the unmodified downscaling filter. The processor may be configured to downscale the video input data using the modified downscaling filter.

摘要： Video pixel line buffers are widely used for data processing in video codecs. Video data may be packed into buffers configured to store a plurality of words, each word comprising a series of bits. The video data may be associated with two or more channels. In order to reduce realization costs, data blocks from two different channels may be packed from opposite sides of a word in the buffer in opposite directions. In some embodiments, data blocks from two or more physical channels may be mapped to two or more virtual channels, the virtual channels having balanced data block sizes. The data blocks associated with the virtual channels may then be packed to one or more buffers.

摘要： Methods, systems, and devices for motion analysis are described. Generally, the described techniques provide for computationally efficient and accurate motion analysis. A device may identify frames of a video frame sequence having a defined resolution. The device may downscale the frames to generate a plurality of downsampled images each having a resolution lower than the defined resolution. The device may generate a respective histogram vector for each pixel of each downsampled image and each pixel of the original frames. The device may determine a motion vector candidate based at least in part on the histogram vectors. The device may apply a filter to the motion vector candidates to determine a final motion vector and output an indication of motion between the frames of the video frame sequence based at least in part on the final motion vector for each pixel of the second frame.
