本文提出了一种技术,用于盲目地消除图像的非线性在没有任何校准信息或明确的成像设备的知识。基本方法利用了非线性在频域中引入特定的高阶相关性(超过二阶)的事实。这些相关性可以使用来自多光谱分析的工具来检测。然后可以通过简单地最小化这些相关性来估计和去除非线性。
This paper presents a technique for blindly removing image non-linearities in the absence of any calibration information or explicit knowledge of the imaging device. The basic approach exploits the fact that a non-linearity introduces specific higher-order correlations in the frequency domain (beyond second-order). These correlations can be detected using tools from polyspectral analysis. The non-linearities can then be estimated and removed by simply minimizing these correlations.
