Publication number: 20080059076Abstract: A method for classifying a plant leaf by utilizing the feature points of venation has been developed. A sample image of the venation can be extracted by utilizing a Curvature Scale Space (CSS) Corner Detection Algorithm. The sample image is treated to thicken the venation and increase the contrast through the retrieval unit prior to applying the Canny Edge Detection technology. The feature point, Branching Point and End Point is detected at each point where the calculated curvature angle is a local maximum. The distribution of the feature points of the extracted venation is calculated by applying a Parzen Window non-parametric estimation method.Type: ApplicationFiled: November 8, 2006Publication date: March 6, 2008Inventors: Hong Keun Choi, Een Jun Hwang, Hyun Chur Shin, Yun Young Nam, Jin Kyu Park
