An easy method for leaf area estimation based on digital images

Manual leaf area estimation is a slow and tiresome process and it is also subjective and inaccurate. A new method is presented in this paper to make this process easier, user friendly and accurate. This paper proposes a new automatic and easy method for leaf area estimation based on digital images of leaves. Researchers can use this method very easily. A standard five rupee coin is used as a reference object to calculate the leaf area. Forty five leaves each of three pulses (i.e. Green Gram, Black gram and Pigeon Pea) have been taken for this study. The Results of our method are comparable to the results of grid paper method. Average accuracy of our method is approximately 97%. Results show that the proposed method is more accurate and user friendly.
