Actually i want to make make landuse using Supervised classification using ground truth data.But i faced a problem,many pixel of other crops they classify in Bare land. Therefore is it possible i made threshold or model that assign Specific pixel values to definite class.
Sir,Actually i performed supervised classification of Landsat 8 image,ERDAS used maximum likehood algorithm for classification but it mingle small class and convert it into a single class.I found many papers about Decision Tree algorithm that even distinguish small difference between small classes.But i do not found procedure how i will make this model and which software is feasible for making this model
You can also try with QUEST in ENVI (see attachment). Or, If you don't have ENVI you can use Erdas expert classification or knowledge engineer to build up your classification.
