The objectives of this project are to study about Near Infrared Spectroscopy (NIRS) as a fruit quality measurement method, to evaluate the use of NIRS for nondestructive measuring SSC of apples and to predict the best model of the measurement data by using Auto-Regressive with Exogenous Input (ARX) Model and Nonlinear Auto-Regressive with Exogenous Input (Nonlinear ARX) Model.
