Abstract: Detecting objects in video may include receiving object detections for a plurality of selected frames of a video from a still image detector, wherein the plurality of selected frames are non-adjacent frames of the video, propagating the object detections from the plurality of selected frames to sequential frames of the video adjacent to the plurality of selected frames based on a distance metric and vector flow data for the sequential frames, suppressing false positive object detections from the propagating, and outputting resulting object detections for the sequential frames of the video.

Abstract: Disclosed approaches for converting between block coded format and raster format include buffers for first type component blocks and second type component blocks of a frame. The buffers are sized less than the width of the frame. A demultiplexer circuit is configured to input the first type component blocks and the second type component blocks in coded block order, and enable storage of the first type component blocks in the first buffer and of the second type component blocks in the second buffer in the coded block order. A multiplexer circuit is configured to flush data from the first buffer in raster scan order in response to a completed set of the first type component blocks in the first buffer, and flush data from the second buffer in raster scan order in response to a completed set of the second type component blocks in the second buffer.
