Title: METHOD AND APPARATUS FOR REMOVING WATERMARK FROM VIDEO
Abstract:
Embodiments of the present application provide a method for removing a watermark from a video. The method comprises: finding a watermark area in a video, and selecting an appropriate watermark extension area; copying pixels of the watermark extension area to form a mask area; extending the watermark area on an original video frame to form a filling area, and filling the watermark area with pixels at the edge of the filling area to obtain a filled video frame; blurring the mask area; and finally, superposing the filled video frame with the blurred mask area, such that the watermark can be completely removed, and moreover, smooth transition between the watermark area and a surrounding area can be ensured.
