Algorithm 2. Secret Reconstruction
Input: Secret shares S1, S2 & S3, number of iterations i
Output: Reconstructed secret Q

Method:
  1. Reconstruct the coefficient matrix H
   H’← S2* S3
  2. Reconstruct the Arnold Transformed Secret QA
   QAS1* H
  3. Apply Inverse Arnold Transform on QA
   Q← Arnold Transform(QA,i)
  4. Reconstruct the secret by Super Resolution
     a. Q″←SRCNN(Q’)
