1. A method for determining a small-object region in a video frame, comprising:

  • dividing a current video frame into at least two regions;

    determining a global motion vector corresponding to each region;

    determining an interframe motion vector of each group of two adjacent frames in multiple video frames that comprise the current video frame and a reference frame of the current video frame;

    determining a candidate small-object region in the current video frame according to the determined interframe motion vector of the each group of two adjacent frames and the determined global motion vector corresponding to each region;

    performing filtering on the candidate small-object region in the current video frame; and

    determining a region obtained after the filtering as a small-object region in the current video frame,wherein the reference frame of the current video frame comprises one or more of preceding continuous video frames of the current video frame and following continuous video frames of the current video frame.
