多帧图像融合提高分辨率的方法研究

Research on improve resolution base on multiple sequences image

多帧图像融合的目的在于复原截止频率之外的信息,以使图像获得更多的细节和信息,提高图像的分辨率。本文阐述了提高图像分辨率的关键技术,从图像匹配和运动估计入手,应用共轭梯度多帧图像融合方法对楔形空间分辨率测试图像进行了方法实验,证实了该方法的可行性与有效性。

Multiple sequences Image fusion can restore spatial frequencies information above the limit frequency to get more details of image and to improve image resolution.This article presents a key technique to improve a high-resolution image,with reduced aliasing,from Multiple sequences image of under-sampled rotated and shifted frames of the same object.Firstly,a digital models of an imaging system are defined to explain image acquisition.Secondly,the image fusion algorithm and the conjugate gradient restoration algorithm are designed.Finally,Simulated experiment results are provided to test our algorithm,with the sphenoid testing image.The results show that theory is robust and telling.
