The real-time detection algorithm of the moving point target inimagesequences is one of the keyalgorithms in manyreal-timeprocessing systems. This paper presents a point-track predicting andmatchingdetecting algorithm after analyzing severallevelmethods of the moving point target in image sequences. Based on theperformance ofsimulation test, we point out theintroduced algorithm can detect low SNR moving point target in image sequenceseffectively. The algorithm can detectmulti-target trajectory in same image sequencessimultaneity.
