| Abstract: | By using image processing,in this paper,a fast way to measure damaged plant leaf area was proposed.Firstly,after image acquisition,pretreatment and geometric rectification,then extracting the outline and filling it and finally,the petiole was removed,the area and damage rate are acquired,which was suitable for different forms of leaves and the area calculation of leaf without damage. |
