Apply image processing technique to determine the correlation of chlorophyll

This paper presents the achievement of determine the chlorophyll using image processing technique. The rice leaf is used to investigate in the experiment in order to chlorophyll directly affects to the rice product. The Linear Regression technique in image processing technique is used to determine the chlorophyll and then compares with the chlorophyll meter. There are 45 rice leafs, which are selected to test in this experiment. The result shows that this technique can provide the average accuracy approximately 95% compared to SPAD measurement.
