Spectral unmixing (SU) is a technique to characterize mixed pixels in hyperspectral images measured by remote sensors. Most of the spectral unmixing algorithms are developed using the linear mixing models. To estimate endmembers and fractional abundance matrices in a blind problem, nonnegative matrix factorization (NMF) and its developments are widely used in the SU problem. One of the constraints which was added to NMF is sparsity, that was regularized by Lq norm. In this paper, a new algorithm based on distributed optimization is suggested for spectral unmixing. In the proposed algorithm, a network including single-node clusters is employed. Each pixel in the hyperspectral images is considered as a node in this network. The sparsity constrained distributed unmixing is optimized with diffusion least mean p-power (LMP) strategy, and then the update equations for fractional abundance and signature matrices are obtained. Afterwards the proposed algorithm is analyzed for different values of LMP power and Lq norms. Simulation results based on defined performance metrics illustrate the advantage of the proposed algorithm in spectral unmixing of hyperspectral data compared with other methods.

由于高光谱传感器的低空间分辨率,高光谱图像包含混合像素。混合像素是包含多个不同材质(称为端元)的像素。混合像元中端元的存在百分比称为丰度分数。光谱解混问题是指将这些像元分解成一组端元和丰度分数。由于丰度分数的非负性约束,非负矩阵分解方法(NMF)被广泛用于解决光谱分解问题。本文采用带稀疏约束的图正则化(GNMF)方法对高光谱数据进行解混。该方法应用于AVIRIS Indian Pines数据集和USGS库的模拟数据,并基于AAD和SAD度量对结果进行量化。实验结果表明,该方法能更有效地对混合数据进行分解。

我们开发了一种新的基于神经网络的独立分量分析(ICA)方法,通过直接最小化所有提取的组件之间的依赖。使用基于矩阵的R{é}nyi的$α$ -阶熵泛函,我们的网络可以直接通过随机梯度下降(SGD)进行优化,而无需任何变分近似或对抗训练。作为一个坚实的应用程序,我们评估我们的ICA在高光谱解混(HU)的问题,并驳斥了一个说法,即“\emph{ICA does not play a role in unmixing hyperspectral data}“,这是最初提出的\cite{nascimento2005does}。我们的DDICA代码和附加说明可在https://github.com/hongmingli1995/DDICA上找到。
