摘要

描述了一种检测和跟踪多个运动物体的方法,该方法使用大空间区域和大时间区域,而不假设时间运动恒定。当分析的大空间区域有多个运动物体时,逐个计算运动物体的运动参数和位置。提出了一种将图像平面分割成不同运动物体并利用两帧计算其运动的方法。描述了利用时间积分对被检测对象进行跟踪,以及通过填充遮挡区域和提高成像对象的空间分辨率来增强被跟踪对象的算法。

Image sequence enhancement using multiple motions analysis
A method for detecting and tracking multiple moving objects, using both a large spatial region and a large temporal region, without assuming temporal motion constancy is described. When the large spatial region of analysis has multiple moving objects, the motion parameters and the locations of the objects are computed for one object after another. A method for segmenting the image plane into differently moving objects and computing their motions using two frames is presented. The tracking of detected objects using temporal integration and the algorithms for enhancement of tracked objects by filling-in occluded regions and by improving the spatial resolution of the imaged objects are described.<>
