Abstract:
This video compression method includes: a step for extracting, from images that constitute a video, regions of interest in which a plurality of target objects are included; and a step for, on the basis of the priorities of the target objects that are determined in advance, controlling the temporal rate for compressing the extracted regions of interest at predetermined compressibility and compressing the video. The temporal rate is higher for a region of interest that includes target objects having a higher priority. In the compression step, for each of regions of interest, a region of interest included in a frame defined by the temporal rate is compressed at a lower compressibility than a region of interest included in another frame.
