METHOD FOR DETERMINING REGION OF SMALL OBJECT, AND METHOD AND APPARATUS FOR INTERPOLATING FRAME BETWEEN VIDEO FRAMES

摘要

Embodiments of the present invention relate to the field of video processing technologies, and in particular, to a method and an apparatus for determining a small-object region in a video frame, so as to determine, in the video frame, the small-object region included in the video frame relatively accurately. The method for determining a small-object region in a video frame provided in the embodiments of the present invention includes: dividing a current video frame into at least two regions, and determining a global motion vector corresponding to each region; determining an interframe motion vector of each group of adjacent frames in multiple video frames that include 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 interframe motion vector of the each group of adjacent frames and the determined global motion vector corresponding to each region; and 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. The embodiments of the present invention achieve an effect of determining, in the video frame, the small-object region included in the video frame relatively accurately.
