Algorithm 2 Algorithm for normalizing a CSD-map

Require:  The original CSD-map image: $OM$  The width of the normalized CSD-map:w  The height of the normalized CSD-map:h Ensure:  The normalized CSD-map: $NM$ 1: $[x,y]=find(OM>0)$; 2: $segm=OM(min(x):max(x),min(y):max(y))$; 3: $NM=imresize(segm,[h,w])$; 4: return $NM$;
