The feasibility of visible and short-wave near-infrared spectroscopy(VIS/WNIR) techniques as means for the nondestructive and fast brand identification of lubricating oil was evaluated. And selected sensitive bands was found validated. 90 lubricating oil samples were randomly selected for the calibration set, while the remaining 90 samples for the prediction set. smoothing way of moving average and...
Based on multi-spectral digital image texture feature, a new method for discriminating tea categories was put forward. The images which have three waveband images (Red, Green, NIR) were recorded by multi-spectral digital imager (MS3100). Eight filters were designed based on discrete cosine transform (DCT), and the NIR image was processed by the 8 filters, then the Standard deviation (Sd) of original...
