Algorithm 3

Merge algorithm.

for 𝑖=0,…,𝑁

 if 𝑅_𝑖 is not merged

  TempR←insert 𝑅_𝑖

  for 𝑖=0,…,𝑁

   if 𝑖≠𝑗

    if 𝑅_𝑗 is not merged

     𝑀𝑅←mean(TempR)

     if distance (𝑀𝑅,𝑅_𝑗)<Th_𝑑

      if intersect (𝐴,𝐵)/(𝑀𝑅_𝑤×𝑀𝑅_ℎ)>Th_𝑟

       TempR←insert 𝑅_𝑗

      end if

     end if

    end if

   end if

  end

  Result ← Add the mean rectangle of TempR

  TempR←∅

 end if

End
