Abstract
Techniques for presenting comments relative to video frames are described herein. The disclosed techniques include obtaining a video comprising a plurality of frames; detecting an edge of at least one object in a frame among the plurality of frames; identifying an area inside the edge of the at least one object as a first area and filling the first area with a color so as to distinguish the first area from others; determining a location of the first area relative to the frame; and determining a movement direction of at least one comment to be presented relative to the frame or a change of a transparency value of the at least one comment to be presented relative to the frame based at least on the location of the first area.
