ridgpolrec

$ \bigcirc$Name


ridgpolrec Get the rectangular frequency grid used to perform ridgelet reconstruction




$ \bigcirc$Command Synopsis


ridgpolrec [-R output_re] [-I output_im] [-C input_im] input_re



-R output_re : real output (2D-FFT image in rect. grid)

-I output_im : imaginary output (2D-FFT image in rect. grid)

-C input_im : imaginary input (2D-FFT image in polar grid)

input_re : real input (2D-FFT image in polar grid)




$ \bigcirc$Function Summary


void ridgpolrec (out_re , out_im , in_re , in_im )

Fimage out_re , out_im ;

Fimage in_re , in_im ;




$ \bigcirc$Description


The module ridgpolrec allows to recover a rectangular frequency grid from the polar frequency grid computed by ridgrecpol, as needed by the ridgelet reconstruction scheme. It uses a nearest-neighbor algorithm described in [SCD02].
