/*================================================================
* function w = intensityWppc(image,pi,pj,rMin,sigmaX,sigmaIntensite,valeurMinW )
* Input:
* [pi,pj] = index pair representation for MALTAB sparse matrices
* Output:
* w = affinity with IC at [pi,pj]
*
pixels i and j (corresponding to the sampling in pi,pj) are fully connected when d(i,j) <= rmin;
% test sequence
f = synimg(10);
[i,j] = cimgnbmap(size(f),2);
[ex,ey,egx,egy] = quadedgep(f);
a = affinityic(ex,ey,egx,egy,i,j)
show_dist_w(f,a);
