Multi-angle and full-Stokes polarization multispectral images using quarter-wave plate and tunable filter

The folder named "MAFS-PMI dataset" contains the multi-angle and full-Stokes polarization multispectral images (MAFS-PMI) dataset. The folder named "MAFS-PMI experimental data" contains experimental data captured to further obtain the MAFS-PMI dataset. The folder named "MAFS-PMI generation code" contains the software code and supporting files to process the MAFS-PMI experimental data and then generate the MAFS-PMI dataset. Details are as follows:

The processed image data of all 12 objects is packaged into "MAFS-PMI dataset.zip". The image data for each object is stored separately in a file labeled as "Object_xx.mat". For example, the file labeled as "Object_01.mat" stores image data for the first object. The data in each file includes 13 variables: a variable for the spectral bands of the liquid crystal tunable filter (LCTF), a variable for the fast axis angles of the quarter-wave plate (QWP), a variable for the incident linear polarization angles of the LCTF, a variable for the preprocessed multi-angle polarization multispectral images, four variables for the derived Stokes polarization multispectral images, two variables for the derived polarization angle multispectral images, and three variables for the derived polarization degree multispectral images. See the file labeled as "readme.txt" in the package for more details.

The raw experimental images of all 12 objects are packaged into "MAFS-PMI experimental data.zip". The folder labeled as "Object_xx" contains images captured for each object. For example, the folder named "Object_01" contains images captured for the first object. A total of 40392 images are captured for 12 objects, accounting for 631 GB. See the file labeled as "readme.txt" in the package for more details.

The experimental data are processed using MATLAB R2019b software to generate the MAFS-PMI dataset. The software code and supporting files that generate the dataset are packaged into "MAFS-PMI generation code.zip". The file labeled as "dataset_generation_main.m" is the main program to process the experimental data to further generate the dataset. The file labeled as "text2trans.m" is the function required to run the main program, implementing the interpolation of the various spectral responses to the same wavelengths. Spectral response files (.txt) for all devices named by their items are provided in the folder "Optical devices", which is also called when running the main program. See the file labeled as "readme.txt" in the package for more details.

名为"MAFS-PMI dataset"的文件夹包含多角度全斯托克斯偏振多光谱图像（MAFS-PMI）数据集。名为"MAFS-PMI experimental data"的文件夹包含为进一步获取MAFS-PMI数据集而采集的实验数据。名为"MAFS-PMI generation code"的文件夹包含用于处理MAFS-PMI实验数据并生成MAFS-PMI数据集的软件代码及支持文件。具体细节如下：

所有12个目标的处理后图像数据被打包为"MAFS-PMI dataset.zip"。每个目标的图像数据单独存储在名为"Object_xx.mat"的文件中，例如"Object_01.mat"存储第一个目标的图像数据。每个文件包含13个变量：液晶可调谐滤波器（LCTF）的光谱波段变量、四分之一波片（QWP）的快轴角度变量、LCTF的入射线性偏振角度变量、预处理后的多角度偏振多光谱图像变量、4个衍生的斯托克斯偏振多光谱图像变量、2个衍生的偏振角多光谱图像变量，以及3个衍生的偏振度多光谱图像变量。更多细节请参见包内的"readme.txt"文件。

所有12个目标的原始实验图像被打包为"MAFS-PMI experimental data.zip"。名为"Object_xx"的文件夹包含对应目标的采集图像，例如"Object_01"文件夹存储第一个目标的采集图像。12个目标共采集40392张图像，总大小为631 GB。更多细节请参见包内的"readme.txt"文件。

实验数据通过MATLAB R2019b软件处理以生成MAFS-PMI数据集。生成该数据集的软件代码及支持文件被打包为"MAFS-PMI generation code.zip"。名为"dataset_generation_main.m"的文件是处理实验数据并生成数据集的主程序；名为"text2trans.m"的文件是运行主程序所需的函数，实现将各类光谱响应插值到相同波长。所有器件的光谱响应文件（.txt格式）按器件名称命名，存放在"Optical devices"文件夹中，运行主程序时会调用这些文件。更多细节请参见包内的"readme.txt"文件。
