图像的亚像素化技术研究

图像匹配在近几十年来一直是人们研究的热点和难点,它是在变换空间中寻找一种或多种变换,使来自不同时间、不同传感器或者不同视角的同一场景的两幅或多幅图像在空间上一致,目前已经应用于许多领域。尤其是多普勒图和医学图像则需要更精确的配准,对于图像处理的许多工作,如运动分析、视频压缩、图像增强和立体视觉同样需要高精度的匹配,即达到亚像素级。本文对图像的亚像素化问题进行研究。

The Research of the Subpixel Image

The image match have been a hot and difficulty in recent decades,it search for one or more transformations in mutative space,and make the two or more image which get from the same scene but from the different times or the different sensor or the different angle of view consistent in space.The image match has been used in many domain.Especially the Doppler image and the medicinal image requires the more precise match.Many work of the image-processing,such as movement analysis,video compression,image potentiation and stereo seeing also requires the high accurate match,namely it needs to reach the subpixel level.The paper discuss the issue of the subpixel image.
