采用非局部均值的超分辨率重构
Super-resolution reconstruction using nonlocal means
摘要
Abstract
As conventional super-resolution algorithms can not implement the motion estimation and reconstruction for an image with local motion in practical engineering applications,this paper proposed a super-resolution reconstruction algorithm based on NonLocal Means (NLM).First,the NLM filter,one of the successful denoising filters in recent years,was introduced briefly.Then,the details concerning its application to super-resolution were analyzed by creating a super-resolution cost function.By considering the practical situations and the need of the engineering facet,a scheme to simplify the procedure in the NLM super-resolution algorithm was proposed.The experiment results show that the simplified algorithm can not only effectively implement super-resolution reconstruction to get a clear and detailed image without explicit motion estimation,but also can obtain a reconstructed speed higher 30％ than that of conventional algorithms.It can satisfy the practical needs of engineering set tings and is expected to reconstruct the high resolution image with complex motion.关键词
