摘要
针对视频运动目标检测领域的研究现状,对帧间差分法、背景建模法、图像分割法、聚类分析法、运动矢量场法等视频运动目标检测方法的算法适应性、复杂度等性能进行了对比分析。辅以典型的视频运动目标检测实例,比较了各种方法的适用范围与优劣特点,可为不同应用场合下视频运动目标检测方法的选择提供参考依据。指出了现阶段视频运动目标检测技术研发的瓶颈所在,以及在新的应用需求背景下所面临的挑战,并对进一步的发展趋势作了预测和评估。
This paper reviews the current development of detection methods for video motion targets, with a comparison of a series of related algorithms, including frame difference method, background subtract method, background modeling, method based on image segmentation, motion vector field analysis method and others, together with their application ranges and complexity. Performances of several target detection methods are tested with video samples, based on which the accuracy, the level of real-time and independency are compared to indicate their applicability and limitations. Moreover, some important issues in engineering applications and possible solutions are proposed based on the current development trends and requirements of practical applications.
