新型湍流图像复原方法的设计与实现

Design and Realization of a New Method for Restoration of Turbulence Image

湍流图像复原方法以图像退化原因为基础,再加上一定的先验知识,建立起相应的退化模型,最后根据建立的模型进行相反运算,达到回恢复原始图像的目的。针对以上问题,本文提出了新型湍流图像复原方法,在本文的湍流图像复原方法中,对待处理湍流图像进行非均匀B样条插值和细节增强等技术处理,相对于目前对于湍流图像复原方法多是理论层的研究,运算量较小,可以实时地复原湍流图像,且本文在对图像的细节增强部分采用空域滤波将低频分量和高频分量分开进行处理的技术。实验结果得到的复原图像的可辨识度更高,并且图像的稳定性也得到了极大的提高。

The turbulence image restoration method is based on the causes of image degradation,plus some prior knowledge,finally the reverse operation is carried out according to the established model,the purpose of restoring the original image is achieved.In view of the above problems,this paper proposes a new turbulence image restoration method,in the turbulence image restoration method in this paper,perform non-uniform B-spline interpolation and detail enhancement on the turbulent image to be processed,compared with the current research on turbulence image restoration methods,which are mostly theoretical level,the amount of calculations is small,turbulence images can be restored in real time,and this paper uses spatial fi ltering to separate the low-frequency components and high-frequency components for processing in the detail enhancement part of the image.the restored images obtained from the experimental results are more recognizable,and the stability of the image has been greatly improved.
