Abstract

The invention discloses a video object tracking method based on a bat algorithm, belonging to the technical field of moving object tracking. The method is characterized by comprising the following steps: 1, determining an initial state vector of an object in an initial frame image of video; 2, establishing a kernel function weighted color model of the object according to the state vector of the object; 3, performing optimization search on the optimal position of the object in next frame image by using the bat algorithm; 4, sequencing a bat swarm according to fitness values to find the state of a bat having maximum fitness value, and positioning the object in the current image according to the state; and 5, judging whether a new image is input in the video or not, if so, continuously executing step 3, otherwise, ending the program. According to the method, the moving object in the video image is tracked by using the bat algorithm, and the state of the bat swarm is updated in real time through dynamic balance of local search and global search, so that an accurate, real-time and robust tracking effect is obtained.

Description

technical field [0001] A video target tracking method based on a bat algorithm belongs to the technical field of moving target tracking. Background technique [0002] Object tracking technology is a research hotspot and difficulty in the field of computer vision. The main purpose of target tracking is to obtain the real-time status of moving targets, and provide a basis for subsequent visual analysis and behavior understanding. Target tracking has been widely used in intelligent video surveillance, intelligent human-computer interaction, video compression coding, robot visual navigation, precision guidance system and other fields, and has extremely broad theoretical and practical research value. [0003] Although researchers have conducted a lot of research on object tracking, many object tracking algorithms have been proposed. Literature (Yilmaz, O.Javed, and M.Shah. "ObjectTracking: ASurvey". ACMCOMPUTSURV, 38(4):1-45 (2006)) and literature (Y.Wu, J.W.Lim, and M.H.Yang. ...
