Spectral unmixing is an important and challenging problem in hyperspectral data processing. This topic has been extensively studied and a variety of unmixing algorithms have been proposed in the literature. However, the lack of publicly available dataset with ground-truth makes it difficult to evaluate and compare the performance of unmixing algorithms in a quantitative and objective manner. Most of the existing works rely on the use of numerical synthetic data and an intuitive inspection of the results of real data. To alleviate this dilemma, in this study, we design several experimental scenes in our laboratory, including printed checkerboards, mixed quartz sands, and reflection with a vertical board. A dataset is then created by imaging these scenes with the hyperspectral camera in our laboratory, providing 36 mixtures with more than 130, 000 pixels with 256 wavelength bands ranging from 400nm to 1000nm. The experimental settings are strictly controlled so that pure material spectral signatures and material compositions are known. To the best of our knowledge, this dataset is the first publicly available dataset created in a systematic manner with ground-truth for spectral unmixing. Some typical linear and nonlinear unmixing algorithms are also tested with this dataset and lead to meaningful results.

Hyperspectral Data Unmixing Using GNMF Method and Sparseness Constraint

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。
