hi i have a project about License plate recognition ..

my project deals only with video sequences taken at night .. i wrote this code to choose a rectangular object from many.. but the problem is that the centroid is sometimes a black pixel and the whole image disappear ... i want a method to choose objects instead of centroid

CODE :

for i=1:numobjects
bo=info(i).BoundingBox;
ratio=(bo(4)/bo(3));
if ratio > option.loc_ratio_value
    cen=info(i).Centroid;
    c(end+1)=cen(1);
    r(end+1)=cen(2);

also in Euler:

for i=1:numobjects
e=info(i).EulerNumber;

if e<option.loc_EulerNum

      cen=info(i).Centroid;
      c(end+1)=cen(1);
      r(end+1)=cen(2);
