A video monitor in multi-target tracking method

The present invention discloses a method of object tracking and fusion ASIFT particle filter characteristics, belonging to the video information processing and pattern recognition art. The method comprising the steps of: deriving a motion video sequence using a target adjacent frame difference method; based on the region corresponding to the complete target acquisition, tracking target model to establish, build and ASIFT feature vector of the target model; Particle filtering prediction candidate target region and construct a candidate target model ASIFT feature vector; target tracking feature vectors with the feature vector matches the target candidate region; false matching using RANSAC algorithm to be removed; update target model, to achieve tracking. The present invention can accurately and quickly track the target at a luminance variation, occlusion, better real-time performance and robustness.
