1. A system for recognizing an object in a video stream, comprising:

  • a memory storing instructions; and

    a processor configured to execute the stored instructions to;

    receive the video stream from a video source, the video stream comprising a first set of video frames;

    select at least one video frame from the first set of the video frames according to a frame selection rate, wherein the frame selection rate determines a number of the selected video frames;

    partition the one or more selected video frames into one or more sets of image blocks, each set of image blocks corresponding to a respective video frame;

    identify, within one or more sets of image blocks, a region which comprise an image of an object, the identification being based on a machine-learning algorithm for determining regions characterized by an image recognition parameter;

    calculate a likelihood metric that the region corresponds to the object;

    adjust the frame selection rate when the likelihood metric is less than a predetermined threshold; and

    display, on a display, information identifying the object.
