The classification post-processing

Why use a classification post-processing ?

• A first classification has been done but some classes are not well-defined or well-recognized .
• In the case of naturally ambiguous classes (as vineyards)
• Other land uses are mixed with the problematic class.

Processing

• Extraction of the mask of the class.
• Computation of factors of the masked image.
• Determination of the crossed histogram.
• Computation of the mixing percentages.
• Determination of the sub-classes.

One can see the vineyards example, or the determination of Alep pines planting density
