Abstract

Embodiments of the present application disclose a method and a device for eliminating video captions. The method comprises the following steps of: obtaining a target video with subtitles to be eliminated, identifying an initial subtitle area of a video frame in the target video, and generating an initial subtitle mask image corresponding to the initial subtitle area; determining a target subtitlemask image corresponding to the current video frame according to the initial subtitle mask image corresponding to the current video frame and the initial subtitle mask image corresponding to the adjacent video frames of the current video frame; wherein the pixel value of the pixel point at the specified position in the target subtitle mask image is obtained according to the pixel value of the pixel point at the specified position in the initial subtitle mask image corresponding to the initial subtitle mask image corresponding to the current video frame and the initial subtitle mask image corresponding to the adjacent video frame of the current video frame; according to the target subtitle mask image corresponding to the current video frame, the current video frame is subjected to subtitleclearing processing. The technical proposal provided by the embodiment of the present application can improve the elimination effect of the video caption.
