Use ERDAS2015 software to perform unsupervised classification of remote sensing images,
A warning message pops up: Covariance calculation requires stack processing but input layer isn't suitable.
Open the calculation result as shown in the figure:
The unsupervised classification results have been calculated as single-band data, but the color assignment of each band is based on the original image, so the image display characteristics are close to the original image.
Although the calculations suggest the above problems, it does not affect the later classification and modification of attributes.
