Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: An app was implemented on android phone to estimate chlorophyll content of corn leaf.New method of imaging, contact imaging, was used to reduce effects of real conditions.Both linear and neural network models re developed to estimate SPAD values.Stepwise and sensitivity analysis re used to extract superior features.The app is a practical and low-cost alternative to measure SPAD. In this study a new android app for smartphones to estimate chlorophyll content of a corn leaf is presented. Contact imaging was used for image acquisition from the corn leaves which captures the light passing through the leaf directly by a smartphone's camera. This approach would eliminate the needs for background segmentation and other pre-processing tasks. To estimate SPAD (Soil Plant Analysis Development) values, various features re extracted from each image. Then, superior features re extracted by stepwise regression and sensitivity analysis. The selected features re finally used use as inputs to the linear (regression) and neural network models. Performance of the models was evaluated using the images taken from a corn field located in st of Ames, IA, USA, with Minolta SPAD 502 Chlorophyll Meter. The R2 and RMSE values for the linear model re 0.74 and 6.2. The corresponding values for the neural network model re 0.82 and 5.10, respectively. Finally, these models re successfully implemented on an app named SmartSPAD on the smartphone. After installing the developed app on the smartphone, the performance of the models re evaluated again using a new independent set of data collected by SmartSPAD directly from maize plants inside a greenhouse. The SmartSPAD estimation compared ll with the corresponding SPAD meter values (R2=0.88 and 0.72, and RMSE=4.03 and 5.96 for neural network and linear model, respectively). The developed app can be considered as a low cost alternative for estimating the chlorophyll content especially when there is a demand for high availability.
