SpectroFood dataset Leek

This dataset contains hyperspectral data in the visible / near-infrared spectral domain for leek. The samples were measured with two sensors FX10 and FX17 capturing the ranges 397.66 - 1003.81 nm and 935.61 - 1720.23 nm, respectively. The mat files 1-6 contain data measured with FX10, while files 7 - 12 contain the FX17 data.

The data set contains cubes of 288 samples, wavelength array and sample labels in Matlab's mat format. Each file captures 48 samples.

This data set exceeds the mean spectra presented in the data paper publication in the journal Data-in-Brief. The mean spectra captured 198 spectral measuring points of FX10, while the present data set also captures the last wavelengths of FX10, resulting in 224 measuring points. The mean spectra captured 223 spectral measuring points of FX17, while the present data set also captures the last wavelength of FX17, resulting in 224 measuring points.

本数据集包含针对韭葱的可见-近红外光谱域高光谱数据（hyperspectral data）。样本由两台传感器FX10与FX17采集，二者的光谱采集范围分别为397.66–1003.81 nm与935.61–1720.23 nm。其中，编号1至6的MAT文件（MAT file）存储FX10的采集数据，7至12号MAT文件则存储FX17的采集数据。

本数据集包含288个样本的高光谱立方体（hyperspectral cube）、波长数组与样本标签，均以MATLAB格式存储；每个文件包含48个样本。

本数据集相较于《Data-in-Brief》期刊发表的数据论文中刊载的平均光谱数据集更为完整：FX10的平均光谱仅涵盖198个光谱测量点，本数据集补充了FX10的末端波段，最终实现224个光谱测量点；FX17的平均光谱涵盖223个光谱测量点，本数据集同样补充了其末端波段，最终同样达到224个光谱测量点。
