Problems solved by technology

At present, more and more videos are captured by cameras embedded in mobile devices such as smart glasses, drones, and mobile phones. Traditional background clipping methods mostly assume that the camera is in a static state, which cannot solve the problem caused by camera movement. interference
In addition, most of the existing object tracking methods for sports cameras do not have the state transition of objects between the foreground and the background, and are not well applicable to first-person videos, such as videos shot through smart glasses.

Abstract

The invention provides a background cutting method and device. The invention can robustly cut out the background area of ​​a video under the condition of camera movement, and realize functions such as object detection, tracking and recognition. The present invention analyzes the input video, combines motion and appearance features, and considers the state transition of the object between the foreground and the background, trains and improves the appearance classifier online, so as to gradually improve the accuracy of the foreground and background classification, and then robustly cut out The background area of ​​the video.

Description

technical field [0001] The present invention relates to the technical field of computer vision, and more particularly relates to a background clipping method and device. Background technique [0002] Background refers to the static part of a scene, and background clipping is widely used in computer vision problems such as video segmentation and object tracking. At present, more and more videos are captured by cameras embedded in mobile devices such as smart glasses, drones, and mobile phones. Traditional background clipping methods mostly assume that the camera is in a static state, which cannot solve the problem caused by camera movement. interference. In addition, most of the existing object tracking methods for sports cameras do not have the state transition of objects between the foreground and the background, and are not well suited for first-person perspective videos, such as those captured by smart glasses. Contents of the invention [0003] The technical problem ...
