Abstract Colourgrams GUI is a graphical user-friendly interface developed in order to facilitate the analysis of large datasets of RGB images through the colourgrams approach. Briefly, the colourgrams approach consists in converting a dataset of RGB images into a matrix of one-dimensional signals, the colourgrams, each one codifying the colour content of the corresponding original image. This matrix of signals can be in turn analysed by means of common multivariate statistical methods, such as Principal Component Analysis (PCA) for exploratory analysis of the image dataset, or Partial Least Squares (PLS) regression for the quantification of colour-related properties of interest. Colourgrams GUI allows to easily convert the dataset of RGB images into the colourgrams matrix, to interactively visualize the signals coloured according to qualitative and/or quantitative properties of the corresponding samples and to visualize the colour features corresponding to selected colourgram regions into the image domain. In addition, the software also allows to analyse the colourgrams matrix by means of PCA and PLS.

Colourgrams GUI：用于分析大型 RGB 图像数据集的图形用户友好界面

Abstract Colourgrams GUI 是一个图形用户友好界面，旨在通过颜色图方法促进对 RGB 图像的大型数据集的分析。简而言之，色图方法包括将 RGB 图像数据集转换为一维信号矩阵，即色图，每一个都编码相应原始图像的颜色内容。该信号矩阵可以依次通过常见的多元统计方法进行分析，例如用于图像数据集探索性分析的主成分分析 (PCA)，或用于量化颜色相关属性的偏最小二乘法 (PLS) 回归。兴趣。Colourgrams GUI 允许轻松地将 RGB 图像的数据集转换为 colourgrams 矩阵，以交互方式可视化根据相应样本的定性和/或定量特性着色的信号，并将与所选颜色图区域对应的颜色特征可视化到图像域中。此外，该软件还允许通过 PCA 和 PLS 分析色图矩阵。
