Abstract
Some embodiments of the present disclosure provide a method for generating video mask information, a method for preventing occlusion from barrage, a server and a client. The method for generating video mask information comprises: identifying, for any video frame in the video data to be parsed, an area where a target object is located in the video frame; selecting a plurality of geometric figures to fit the area where the target object is located, to allow a combination of the plurality of geometric figures to cover the area where the target object is located; and generating the mask information of the video frame according to a fitting parameter of the plurality of geometric figures, and sending the mask information and data of the video frame to a client synchronously. Some embodiments of the present disclosure are adopted to avoid occlusion caused by the barrage information on the video image while the vast majority of the barrage information remains and reducing a bandwidth consumption of the client.
