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.
