Adaptive thresholding for computer vision on low bitrate compressed video streams

A system for applying computer vision to decompressed video comprising:

• a memory to store an individual video frame and a reference video frame;
• and
• a processor coupled to the memory, the processor to:
• generate a region of interest in an individual video frame by translating one or more spatial indicators of a first detected computer vision result in a reference video frame to the individual video frame;
• compare a first computer vision score for a first location of the individual video frame to a first threshold and a second computer vision score for a second location of the individual video frame to a second threshold to determine whether the first score or the second score corresponds to a second detected computer vision result, wherein the first threshold is less than the second threshold in response to the first location being within the region of interest and the second location being outside of the region of interest;
• and
• transmit an indicator of a second detected computer vision result when the first score compares favorably to the first threshold or the second score compares favorably to the second threshold.

At least one non-transitory machine readable medium comprising a plurality of instructions that, in response to being executed on a device, cause the device to apply computer vision to decompressed video by:

• generating a region of interest in an individual video frame by translating one or more spatial indicators of a first detected computer vision result in a reference video frame to the individual video frame;
• comparing a first computer vision score for a first location of the individual video frame to a first threshold and a second computer vision score for a second location of the individual video frame to a second threshold to determine whether the first score or the second score corresponds to a second detected computer vision result, wherein the first threshold is less than the second threshold in response to the first location being within the region of interest and the second location being outside of the region of interest;
• and
• transmitting an indicator of a second detected computer vision result when the first score compares favorably to the first threshold or the second score compares favorably to the second threshold.
