ridgthres

$ \bigcirc$Name


ridgthres Image denoising by means of ridgelet thresholding




$ \bigcirc$Command Synopsis


ridgthres [-I in_im] [-C output_im] in_re np pourcent out_re



-I in_im : imaginary input (Fimage N*N)

-C output_im : imaginary output (Fimage N*N)

in_re : real input (Fimage N*N)

np : resolution np

pourcent : percent of conserved coeff

out_re : result (Fimage N*N)




$ \bigcirc$Function Summary


void ridgthres (in_re , in_im , np , out_re , out_im , pourcent )

int np , pourcent ;

Fimage in_re , in_im ;

Fimage out_re , out_im ;




$ \bigcirc$Description


The module ridgthres is a basic example of the use of Ridgelet in image denoising : only highest coefficients of the ridgelet decomposition are kept while others are discarded. This leads to an image with enhanced straight lines.
