TESTTIGHTNESS

Test Tightness of PPFT

Contents

Description

OUTPUT_TESTTIGHTNESS=TESTTIGHTNESS(N,R,BETA,Choice,REPS,LFILE)
   Generate images I_1,...,I_REPS of size N,
   oversampling rate R, basis CHOICE (see basisFunction), and
   randomly wth normally distributed entires. Compute
   M_{tight_1} = \max_{i=1...reps} norm(S^\star SI_i-I_i,'fro')/norm(I_i,'fro').
   M_{tight_2} = \max_{i=1...reps}norm(CG(I_i)-I_i,'fro')/norm(I_i,'fro');
   Here S is the shearlet transform, CG using cg iteration for PPFT.
