Image Based Leaf Area Measurement Method Using Artificial Neural Network

Leaf area is an important parameter in plant monitoring. An automatic method for measuring leaf area is needed to obtain accurate result. In this paper, a method for automatic leaf area measurement from image is proposed. The method captured the image of leaf without object reference. Four features were extracted from the image and used as input to artificial neural network for estimating leaf area. The experiment results show that the proposed method can measure leaf area with mean absolute relative error less than 1% and less computational time.
