| 摘 要： | 条带噪声是影响Modis影像质量和反演精度的重要因子，有些在频率域表现为高频信息和低频信息相混合。针对条带噪声形成的原因和规律性，以及对影像进行傅立叶变换频谱分析，比较了几种常用条带噪声去除方法及其局限性。提出了邻域插值法，编程实现自动定位噪声行，进行插值处理，取得了较好的去噪效果，并保留了影像的细部特征。

| Abstract: | Stripe noise is the important factor that affects the Modis quality of an image and retrieving precision. In frequency region, the expression is mixed with the composition information of low frequency and high frequency. According to the regularity and reason that stripe noise forms, as well as analyze the frequency spectra of an image carry out Fourier transform. Compare some kinds of methods on removing stripe noises and its limitation. Put forward neighboring-region interpolation algorithm, program realizes automatic location noise stripes, carry out interpolation handling. At the last, obtain better remove noises effect, and retain the detail features of images. |
