I am trying to classify the 3 bands RGB image in ArcMap 10.8 using Image Classification toolbar. I have prepared some training samples, and performed the Maximum Likelihood Classification. The result is returning 3 classes instead of all 6 classes that the training samples have.
As I completed the same classification on another 4 bands RGB image, and I had similar number of training samples, image was the same size, I have used the same algorythm, and everything worked well, now I have no idea why is that no longer working on the 3 bands image.
Of course I have generated new signature file for new image, and set the right inputs.
What could be the cause of my problem?
