Fusion algorithm example to split a picture into different areas depending on their average color

function [res labelMax] = partoche(img,seuil,n)
    taille=size(img(:,:,1));
    res = ones(taille)*n;
    labelMax = n+1;
    if taille(1) >= 8 && taille(2) >= 8    
        if zoneHomogene(img,res,n,seuil) == 0,
            moitieX = round(taille(1)/2);
            moitieY = round(taille(2)/2);
            [res(1:moitieX,1:moitieY) labelMax]= partoche(img(1:moitieX,1:moitieY,:),seuil,n+1);
            [res(moitieX+1:taille(1),1:moitieY) labelMax]= partoche(img(moitieX+1:taille(1),1:moitieY,:),seuil,labelMax);
            [res(1:moitieX,moitieY+1:taille(2)) labelMax]= partoche(img(1:moitieX,moitieY+1:taille(2),:),seuil,labelMax);
            [res(moitieX+1:taille(1),moitieY+1:taille(2)) labelMax]= partoche(img(moitieX+1:taille(1),moitieY+1:taille(2),:),seuil,labelMax);
