Abstract

For the image shot by the CCD camera fixed on the moving carrier (such as plane or ship), there is the whole image movement by the movement of carrier besides the movement of targets. For detecting moving targets in the moving background and tracking them, an arithmetic based on wavelet transform multi-layer block matching tracking is suggested in this article. The wavelet of bior1.3 is used to decompose image. It is anti-symmetric wavelet and is fit for detecting variation information in horizontal and vertical direction. It can use many layer son-image to match and the vector of the whole background can be estimated. It can detect moving targets from the background by difference arithmetic, and can work out the figure center of target, and trace out the movement contrail of the targets. Compared with traditional block matching tracking arithmetic, it overcome some disadvantages, such as a mass of operation, inaccurate matching in the low SNR image. Otherwise the matching in N×N area in son-image is equal to the matching in 2nN×2nN area in oral image. The searching speed is faster than before. The experiment is done while the moving vector of two neighbor frame is less then 10 pixel and the moving vector of the moving targets in background is less then 5 pixel. The availability and feasibility of this arithmetic is proved by the result.
