In order to achieve fast and accurate acquisition of area and color feature parameters of plant leaves, a simple and easy-to-operate digital image resolution system is designed based on the Matlab Graphical User Interface (GUI) platform. This system enhances the accuracy of leaf area calculation through processing of grayscale changes, image segmentation, morphological analysis, median filtering, etc. Through the design of six edge detection operators, the system can meet the recognition requirements of different types of leaves. The color recognition module extracts color parameters of leaves using the Red Green Blue (RGB) color model, Hue Saturation Value (HSV) color model, and Lab color model. It then generates histograms for each color component. The results show that this method for extracting leaf characteristics is convenient, accurate, non-destructive, and can be applied to common leaf growth states.
