Original data from a research for developing hue change phenomenon into mature quantitative chemical analysis technique (including chemical imaging)

We proposed a novel hue descriptor (Huev) with a tunable hue quantification sequence via Hue Threshold (HT) to solve the problem that the hue quantification sequences of existing quantitative parameters are fixed and lack adaptability to diverse hue change sequences of multi-hue optical sensors. Then we systematically investigated how to correlate Huev with quantitative analysis (including chemical imaging) of multi-hue optical sensors, and developed a user-friendly analysis platform (composed of a machine vision device and a IQA software) to facilitate the application of this method. The wider applicability of Huev than existing parameters, and the practicability of this method in mean analyte concentration measurement and chemical imaging were proved. All raw data of the figures in main text and extended data were shown here. The structure and content of the dataset were presented in the README.txt file. When comparing Huev with existing parameters, we used these parameters to analyze many sensor images from published literature. Snipaste software was used to cut sensor images from the literature downloaded in PDF format for further analysis. These literature titles were presented in the References section of this upload.
