Abstract: It integrates traditional chemical analysis methods with digital image processing techniques. By systematically analyzing the correlation between the concentration of substance solutions and the color parameters of digital images, a multiple regression prediction model based on color feature values is established. To facilitate the intelligent transformation of analytical techniques, a Graphical User Interface (GUI) based on the MATLAB platform is developed. This GUI enables a one-stop analysis process encompassing "image feature input-automatic model calculation-instant concentration display".
