Bonsoir!
Je suis entrain de faire la classification dans le logiciel ENVI 5.3.
Je suis arrivé à une option que je maitrise pas beaucoup, j'aimerais avoir une interprétation et l'impact de l'augmentation et reduction des deux chiffres.La partie c'est Cleanup_Refine Results.
il y a d'abord: Enable somoothing__Smooth kernel Size 3;
et Enable aggregation__Aggreagate Minimum Size : 9.
Merci de me faire un retour!

The description of this process is here:

Regarding the smoothing kernel size, increasing the size will reduce spatial resolution (meaning the image will appear blurrier); this also reduces noise and sharpness.
Our staff and staff from other DAACs will provide additional information soon.
