1st you can select the class by SELECT --> Select By attributes tool (once the selection is over) you can use  DATABASE MANAGEMENT --> GENERAL --> Merge tool to merge the selected classes ( ArcGIS software)

Use Image classification tool of both Erdas & ArcGIS do the supervised classification techniques for output layer result.

Better if you can do in ERDAS IMAGINE although it is also possible in arc GIS

Do both unsupervised classification of K-MEANS AND ISODATA ANALYSIS then do the supervised classifications Use ERDAS IMAGINE AND ENVI both remote sensing software's to find an output result in any change detection's data analysis.
