Method for generating video mask information, method for preventing occlusion from barrage, server and client

The method of claim 1, wherein selecting a plurality of geometric figures to fit the area where the target object is located comprises:

• dividing the area where the target object is located into one or more sub-areas according to physical features of the target object;
• selecting, for any of the sub-areas, a geometric figure fitting with the sub-area, and determining a layout parameter of the geometric figure, to allow the geometric figure drawn according to the layout parameter to cover the sub-area;
• and
• generating a fitting parameter of the geometric figure according to a type of the selected geometric figure and the layout parameter of the selected geometric FIG. 7. The method of claim 6, wherein generating a fitting parameter of the geometric figure comprises:
• identifying a preset graphic identifier corresponding to the type of the geometric figure, coding the preset graphic identifier and the layout parameter respectively, and taking coded data as the fitting parameter of the geometric figure.

A server, comprising at least a processor and a memory, the memory being used to store computer-readable instructions which, when being executed at least a processor, performs a method for generating video mask information;

• wherein the method comprises:
• reading video data to be parsed, and identifying, for any video frame in the video data, 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 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.

A method for preventing occlusion from barrage, wherein the method comprises:

• receiving video data and barrage data sent by a server, wherein the video data includes at least mask information of a video frame, and the mask information includes a fitting parameter of a plurality of geometric figures;
• wherein a combination constituted by the plurality of geometric figures covers a target object in the video frame;
• parsing the mask information of the video frame to determine, in the video frame, an area where each of the geometric figures is located according to the fitting parameter of the plurality of geometric figures;
• and
• displaying no barrage data corresponding to the area where each of the geometric figures is located when the barrage data is rendered in the video frame.
