A device may receive and store video frames in the memory. The device may define, in a video frame among the video frames, a plurality of bounding boxes to visually bound one or more subjects, each bounding box of the plurality of bounding boxes may be defined in accordance with a pre-defined aspect ratio, and each bounding box may comprise padding above and laterally with respect to the one or more subjects in the video frame. The device may reduce the plurality of bounding boxes by merging two bounding boxes among the plurality of bounding boxes to create a merged bounding box, wherein the merged bounding box may maintain the pre-defined aspect ratio and visually bounds the two bounding boxes being merged, and wherein the reduced plurality of bounding boxes is provided to an object detector.

System and method for bounding box merging for more efficient secondary analysis in video frame processing

A device for efficient object detection and selective display of video frames is disclosed. A plurality of bounding boxes to visually bound one or more subjects are defined in the received video frames; each bounding box includes padding above and laterally with respect to the one or more subjects in the video frame. The device may reduce the plurality of bounding boxes by merging bounding boxes to create reduced plurality of merged bounding boxes. The device performs object detection on the reduced plurality of merged bounding boxes by searching a training database for detecting and identifying suspicious objects. The identified objects are annotated. On identifying that an object is suspicious, based on a trained database of firearms in a plurality of environments across a plurality of industries, the video frame is transmitted to a graphical user interface of a user device.
