US 12,705,891 B2 · Methods and apparatus for generating images of objects detected in video camera data

Abstract

A non-transitory, processor-readable medium stores instructions that, when executed by a processor, cause the processor to receive video-derived detection data associated with a plurality of persons. For a first person from the plurality of persons, a portion of the video-derived detection data associated with the first person is assigned to a first motion track based on a motion model, and a closeup image of the first person is generated based on the portion of video-derived detection data. A quality score is generated based on the closeup image, and the closeup image is assigned to the first motion track based on the quality score. The first motion track is selected from a plurality of motion tracks associated with the plurality of persons. Using a neural network, first identity data is generated based on the closeup image, and the first motion track is updated based on the first identity data.

A non-transitory, processor-readable medium storing instructions that, when executed by a processor, cause the processor to:

receive video-derived detection data associated with a plurality of persons;
for a first person from the plurality of persons:
assign a portion of the video-derived detection data associated with the first person to a first motion track based on a motion model,
generate a closeup image of the first person based on the portion of video-derived detection data,
generate a quality score based on the closeup image, and
assign the closeup image to the first motion track based on the quality score;
select the first motion track, from a plurality of motion tracks associated with the plurality of persons, based on at least one of the quality score or a previous selection of a second motion track (1) associated with a second person from the plurality of persons and (2) from the plurality of motion tracks;
generate, using a neural network, identity data based on the closeup image;
and
update the first motion track based on the identity data.

An apparatus, comprising:

a processor;
and
a memory operably coupled to the processor, the memory storing instructions to cause the processor to:
receive a video stream including a sequence of video frames;
generate a compressed sequence of video frames based on the sequence of video frames;
generate, using a first neural network and based on the compressed sequence of video frames, a detection of a first person and a detection of a second person;
assign (1) the detection of the first person to a first motion track and (2) the detection of the second person to a second motion track different from the first motion track;
generate, based on the detection of the first person, a first image that depicts at least a portion of the first person and that includes a cropped portion of a first video frame from the sequence of video frames;
generate, based on the detection of the second person, a second image that depicts at least a portion of the second person and that includes a cropped portion of a second video frame from the sequence of video frames;
generate (1) a first quality score for the first image and (2) a second quality score for the second image;
select the first motion track based on at least one of (1) the first quality score being above a predefined threshold value, (2) the first quality score being greater than the second quality score, or (3) a previous selection of the second motion track;
in response to selecting the first motion track, generate, using a second neural network, identity data for the first person based on the first image;
and
cause display, via a graphical user interface (GUI), of a representation of the identity data.
