中文摘要针对神经网络非均匀性校正算法(NN-NUC)存在的鬼影问题,分析了其形成的机理,提出一种自适应非均匀性校正算法.首先设计了一个去噪保边的高斯低通-三边联合滤波器;然后采用该滤波器取代NN-NUC算法的均值滤波器获取期望图像,以减少边缘像素估计误差,达到抑制鬼影的目的。采用仿真和实际红外图像序列进行实验的结果表明,该算法在有效地抑制鬼影的同时获得了较好的非均匀性校正效果。
英文摘要Ghosting artifact exists in Neural Network nonuniformity correction(NN-NUC) algorithm. The cause of ghosting artifact is analyzed, and an adaptive nonuniformity correction algorithm is proposed. First, an edge-preserving and denoising filter combinated by Gaussian low-pass filter and trilateral filter is designed. Then, the spatial average filter of NN-NUC is replaced by the proposed filter. To a large degree, the estimating errors of edge pixels are reduced and the ghosting artifact is removed. Finally, a simulation and a real infrared image sequence testing are carried out. The results show that the proposed algorithm effectively mitigates the ghosting artifact and yields a good nonuniformity correction effect.
