The realistic mixing miniature scenes (RMMS ) dataset

The RMMS dataset was collected by a push-broom hyperspectral spectrometer, which can be used to quantitatively evaluate the unmixing accuracy of different algorithms. It consists of a linear mixture scene with homogeneous flat materials and a nonlinear mixture scene with three-dimensional structural features. The features of the RMMS dataset also take point, line, and plane characteristics into consideration, and their spectral similarity increases the challenge of spectral unmixing. Category: linear mixture scene data and nonlinear mixture scene data.

RMMS数据集由推扫式高光谱光谱仪（push-broom hyperspectral spectrometer）采集，可用于定量评估不同算法的光谱解混精度。该数据集包含两类场景：一类为具备均质平面材质的线性混合场景，另一类为带有三维结构特征的非线性混合场景。RMMS数据集的特征同时兼顾点、线、面三类特性，其光谱相似度进一步提升了光谱解混的任务难度。数据集类别分为线性混合场景数据与非线性混合场景数据。
