摘要:
为了提高被动毫米波图像分辨率,该文将凸集投影算法(POCS)应用于被动毫米波图像的超分辨率恢复中。文章对引起被动毫米波成像系统图像降质的因素进行了分析和讨论,建立了成像模型,结合POCS算法原理,利用图像的噪声统计特性以及幅度约束条件,对POCS算法用于被动毫米波图像的超分辨率恢复进行了详细分析,并给出了算法流程。仿真结果表明:POCS算法用于被动毫米波图像的超分辨率恢复相对双线性差值方法恢复效果有明显改善。
Abstract:
In order to improve the resolution o f image acqu ired by passive m illimeter-wave ( PMMW ) rad iom eter, a pro jection onto convex se ts ( POCS) approach to PMMW image super-resolution restoration is presented. The factors that cause the image o f the PMMW imag ing system to be blurred are analyzed, and the PMMW imag ing model is set up. Comb in ing w ith the principle o f the POCS algorithm, th is paper adopts the priori statistica lknow ledge of the system no ise as a restrict cond ition and d iscusses the imp lem entation of the POCS algorithm applied in the super-reso lu tion restorat ion o f PMMW im ages. The flow chart o f the algorithm is also presented. The simulat ion results demonstrate that the POCS approach for PMMW image resto ration can get better results compared w ith the b ilinear- interpo lation algor ithm. The effic ient imp lem entat ion o f this algorithm proves that it is su itable for the applicat ion of passivem illimeter-w ave image restora tion.
