FTCF

the operator F^*CF applying to a vector x and F is the operator PPFT.

Contents

Description

 Here F denotes the operator of the pseudo-polar transform and
 C is the weights on the pseudo-polar grid. F^* is the adjoint.

 Y = FTCF(X,C) return y = F^*CF(x), i.e., first apply the pseudo-polar
 transform to x, then apply the weigting on the resulted image, and
 the apply the adjoint pseudo-polar transform to the weighted image.

Examples

       n = 10; R = 2;
       x = randn(n);
       C = ones(2,R*n+1,n+1);
       y = FtCF(x,C);
