An algorithm based on Beamlet Transform is proposed.Having dyadic and recursive subdivision on image,intgrating on Beamlets in each subsquare,the straight lines are approximated under GLRT(Generalized Likelihood Ratio Testing).This method can overcome all kinds of noise in images and can extract exactly straight lines even in low SNR images.
