Hi all! i hope this is a right place to write my problem with maximum likehood classification. The first time i tried this classification, i got a result with nothing but a black screen in both labeled class band and both confidence band(i used’train on vector’ option). and after i tried a second time with another image(it was a change detection image) for maximum likehood it has both labeled class and confidence band. lastly when i try the ‘train on raster’ option on first image i had labeled class as black screen while had confidence band with some results. Since it was my first time of try it could you explain me what does labeled class and confidence band means? and why did it result as very different each time? how to get rid of getting black screen?
images of spoken topic are shown below
the first try image with geometries that i used on it
the results of first try
the results with change detection labeled class
the results with change detection confidence band
the lastly results of first image with ‘train on raster’ option
