Map video generation method and device

Abstract

The invention discloses a map video generation method. A PISA algorithm is used to find out a significance area in a video frame, and a target area is determined according to the size of the significant area and is tracked. The map content is synthesized into a video according to a tracking data file. The invention further discloses a corresponding map video generator and a map video generation client. A user adds a map to a video frame, and the map can automatically move along with a target during a video playback process. The map no longer stays silly at a fixed position. The intelligence of a map video technology is improved. The interaction quality is effectively improved.

Description

Technical field [0001] The invention relates to the field of multimedia, in particular to a texture video generation method, a texture video generator and a texture video generation client. Background technique [0002] The existing video mapping technology is mostly static mapping, that is, people manually add the content of the texture to the static video frame. The content of the texture can only be displayed on the current frame of the addition or texture. If you want to achieve a video with the same texture, You need to manually process each frame of video, which is a huge workload. [0003] With the development of mobile short video APP, some APP software that adds video textures in batches has also appeared, but its application technology is also similar to adding textures to static frames. A fixed position is preset for each texture or manually by the user. Determine a position, and then the position of the texture remains unchanged throughout the video. [0004] Video belo...
