Abstract

The invention discloses a motion foreground detection method and device, terminal equipment and a storage medium. The method comprises: obtaining a to-be-detected current video frame; when the current video frame is the first frame of picture, initializing a pre-established first Gaussian mixture model by using the pixel value of each pixel point of the current video frame; otherwise, performing motion vector estimation on the current video frame according to the background frame to obtain a global motion estimator of the current video frame; performing position correction on the first Gaussian mixture model of each pixel point in the current video frame according to the global motion estimator; matching each pixel point of the current video frame with the first Gaussian mixture model of which the position is corrected; and classifying each pixel point in the current video frame into a foreground pixel point and a background pixel point according to a matching result. According to the invention, the problem of missing detection of the motion foreground in a current motion foreground detection method in a dynamic scene can be solved.

Description

technical field [0001] The present invention relates to the technical field of computer image processing, in particular to a moving foreground detection method, device, terminal equipment and storage medium. Background technique [0002] In the field of computer digital image processing, moving foreground detection based on image processing refers to distinguishing moving foreground objects from background in video sequences. According to the motion state of the shooting picture, the moving foreground detection algorithm can be divided into the foreground detection method under the static background and the foreground detection method under the dynamic background. The static background corresponds to the scene where the camera is fixed and the background is relatively stable; the dynamic background includes two situations, one One is that the camera is fixed, but the shooting picture contains a moving background, such as shaking leaves, water ripples, etc.; the other is that...
