An Image Processing Based System for Leaf Parameter Measuring

Based on digital image processing technique, the paper studied and implemented an image analysis software system of foliage feature parameters. The system integrated the methods of Image enhancement, morphological processing and boundary tracking to preprocess the photo image of plant leaves that contains the calibration object; use the boundary tracking to get the boundary information, use the boundary chain code method the pixel method, the minimum external rectangle (MER) and other methods to measure the more than ten general characteristics of the leaf perimeter, including the parameters, area and rectangular. The results showed that measurement accuracy can basically meet the requirements of botanical investigation.
