| Research Abstract |
Bruising is one of the most common causes for the degradation of fruit quality. Therefore, it is necessary to distinguish bruised fruit from undamaged fruit to improve fruit quality. Currently, the detection and removal of bruised apples has predominantly been performed manually, which is subjective, inefficient and expensive. In the present research, five methods of wavelength selection, ROC-based selection, CSMW-LS-SVM selection, VIP selection, GA selection, and VIP-GA selection, were studied to select the effective wavelengths for bruise detection within 380-1000 nm spectroscopy for four cultivarsof apples, Fuji, Jonagold, Orin, and Sinano Gold.
