Abstract

The invention discloses a ghost quick-inhibition method based on a ViBe algorithm. The method is characterized by comprising the following steps: step SS1, inputting a video sequence, detecting the video sequence by using a ViBe algorithm, judging whether the video sequence is a background or not, updating a background model if the video sequence is a background, or going to step SS2; step SS2, performing ghost detection on the video sequence in step SS1, judging whether the video sequence is a ghost, judging the video sequence as a background and updating the background model if the video sequence is a ghost, or going to step SS3; and step SS3, judging the video sequence as a foreground and outputting the foreground. By adopting the method of the invention, that a background model does not absorb a transitorily still target quickly is ensured while a ghost can be inhibited quickly.

Description

technical field [0001] The invention relates to a fast ghost suppression method based on a ViBe algorithm, which belongs to the technical field of signal and information processing. Background technique [0002] In 2009, Olivier Barnich and Marc Van Droogenbroeck first proposed to apply the concept of random set to the field of foreground extraction of moving targets, and named this algorithm ViBe (Visual Background Extractor) algorithm. The ViBe algorithm uses a random strategy to select the sample values ​​that make up the pixel model. Secondly, the ViBe algorithm proposes a strategy of disseminating information between adjacent pixels of an image according to the principle of spatial consistency of image pixels. In addition, it adopts the method of instantaneous initialization, which can make the ViBe algorithm work from the second frame of the image sequence. [0003] However, it is this instantaneous initialization method that causes the ghosting problem in the ViBe a...
