| Abstract: | 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. |
