Features Extraction of Moving Target Image Based on Nuclear Method and Spatio-Temporal Correlation Theory

For the detection of moving targets, we firstly discuss the background difference method, inter frame difference method, optical flow method to the traditional detection method, and points out their respective scope of application and the advantages and disadvantages, and in this foundation proposed moving target detection scheme based on temporal and spatial correlation to better solves the traditional moving object detection methods have some defects, improve the quality of target detection. This paper described the background estimation of target detection and extraction method and several common background estimation algorithm based on, through multi frame combined to achieve the fixed scene under the background of the recovery algorithm, gives the corresponding experimental results. By tracking template and consecutive frames difference profile of coarse contour tracking, to avoid the traditional tracking method to match and search the large computational problems and fixed size matching template for non rigid object tracking the false detection problem.
