#### *5.1. Winter Crop Types Classification Methods Comparison*

The classification results of the different approaches and methods of the winter wheat and winter barley and their accuracy analysis are presented in this part. Firstly, the results of PBC and OBC of each step in the hierarchical classification are demonstrated and evaluated through accuracy assessments, the more accurate results were retained for further processing and comparison with classical direct extractions. Then the final results of the hierarchical classification and classical direct extraction are displayed and compared with accuracy assessments as well.
