FSD-HSO Optimization Algorithm for Closed Fringes Interferogram Demodulation

Algorithm 1

The improvisation procedure of HSO.

Generate the HM (initial harmonics as real number arrays)

Define the PAR

Define the HMCR

while (Max number of iterations > SC)

 Create new harmonics by accepting better harmonics

 Adjust PAR to take new solutions (harmonics)

  if (rand > HMCR)

    Choose an existing harmonic randomly

  else-if (rand > PAR)

    Adjust the pitch randomly within a bandwidth (bw)

  else

    Create new harmonics via randomization

  end if

 Accept the new solutions (harmonics) if better

end while
