• That is one REALLY cool page! --Mboutin 12:44, 23 September 2009 (UTC)
• What did you do to apply the lowpass filter? -- weim
• lpf = firpm(500,[0 1e-12/D 2e-12/D .5]*2,[1 1 0 0]);
• g_final = filter2(lpf,g_up);
• g_final = D*g_final;
• g_final is the resulting image and g_up is the upsampled version of the original,
• firpm(500,... generates a 500 order Parks-Mc Clellen filter of cutoff. MATLAB uses 1 as pi and 1e-12 and 2e-12 are the cutoff frequencies on the scaled pi axis f = 2.pi.fmax(f) the way we did in class
