This is the first time that a low-cost system was designed for measuring leaf nitrogen level using the reflectance at 12 wavelengths. KNN can achieve higher accuracy when the number of training samples is much larger than the number of features [50]. However, there is no universal classifier...
The other reason is that the cost of hyperspectral cameras has been significantly reduced due to the rapid development of relevant technology. Therefore, hyperspectral imaging has become a popular tool for object detection and recognition. The structure of a hyperspectral image is in a 3D data cube...
