摘要

多片CCD拼接遥感成像系统由于存在非均匀性问题，导致遥感图像中常存在条带噪声，本文在分析条带噪声的主要来源和模型的基础上，提出了多尺度变分模型的条带噪声去除方法。首先，分析了条带噪声的特点并建立了图像退化模型。其次，结合条带噪声的单向性特点与多尺度分层分解方法构造能量泛函。然后，利用不动点Gauss-Seidel迭代法多尺度分级极小化能量泛函，将条带噪声和图像有用信息分离。最后，对各尺度结构分量和细节分量进行累加，得到去噪图像。实验结果表明：对于周期条带噪声，图像畸变量为2‰，图像辐射质量提升到11.715 dB；对于随机条带噪声，图像畸变量为3.3‰，图像辐射质量提升到11.092 5 dB。与典型条带噪声去除方法相比，不管是周期条带噪声还是随机条带噪声，本文方法均能够在保证畸变量很小的情况下，将其完全去除，满足遥感图像低畸变量的预处理要求。

Abstract

Non-uniformity often occurs in multi-detectors remote-sensing imaging system

resulting in the existence of strip noise in remote sensing images. A destriping method with multi-scale variational model has been proposed on the basis of the analysis on the main sources and model of stripe noise. First

the characteristics of strip noise have been analyzed and the degradation model of the image has been formulated. Secondly

the unidirectional characteristic of strip noise and multi-scale hierarchical image decomposition have been combined to structure

-functional. Then

the method uses fixed point Gauss-Seidel iterative method to minimize multi-scale

-functional and separate stripe noise and useful information. Last

structural and details component under different scales will be accumulated to obtain the destriped images. The experiment result on real remote sensing images indicates that the image distortion is 2‰ and IF increases to 11.715 0 dB for regular stripe noise; the image distortion is 3.3‰ and the IF increases to 11.092 5 dB for random stripe noise. Compared with typical destriping methods

the method in this paper can ensure that stripe noise will be removed completely and pre-processing requirements of small distortion for remote sensing images will be met

for both regular stripe noise and random stripe noise.
