| 摘 要： | 运动估计技术是计算机视觉和视频信号处理的关键技术之一,近年来广泛应用于各种视频通信标准中.由于表观运动和实际运动的差异以及孔径问题和遮挡问题的存在,使运动估计难以精确.为此提出一种基于亮度和运动联合分割的位移场估计算法,试图用分割的结果指导运动估计过程,获得了满意的结果.

| Abstract: | Motion estimate is a key technology in computer vision and video signal processing. It is widely used in international standards for video communication. Due to the difference between real motion and apparent motion and the existence of the aperture and the occlusion problem, it seems difficult to obtain the precise motion field. In this paper, we present a displacement field estimate algorithm based on joint luminance and motion segmentation to obtain a satisfactory result. |
