Non-destructive method for discrimination of weedy rice using near infrared spectroscopy and modified self-organizing maps (SOMs)
Weedy rice, particularly paddy seed, is difficult to handle and separate because it has characteristics (morphological likeness) similar to those cultivated rice. This research describes a modification of self-organizing maps (SOMs) for categorizing weedy rice from cultivated rice using near-infrared spectroscopy (NIR) on paddy seed in situ. Optical microscope and thermogravimetric analysis were employed to …
