c# - Making graphic object selected -

-

hi want make graphic object "selected" after click on them.

i tryied make selected line:

else if (e.originalsource line)         {             linefocus = true;             mojalinia = (line)e.originalsource;              rectangle rect_1 = new rectangle             {                 stroke = brushes.black,                 strokethickness = 1,                 fill = new solidcolorbrush(color.fromrgb(255, 255, 255))             };             rect_1.width = 6;             rect_1.height = 6;              canvas.setleft(rect_1, mojalinia.x1);             canvas.settop(rect_1, mojalinia.y1);             canvas.children.add(rect_1);             rectangle rect_2 = new rectangle             {                 stroke = brushes.black,                 strokethickness = 1,                 fill = new solidcolorbrush(color.fromrgb(255, 255, 255))             };             rect_2.width = 6;             rect_2.height = 6;              canvas.setleft(rect_2, mojalinia.x2);             canvas.settop(rect_2, mojalinia.y2);             canvas.children.add(rect_2);         }

its bit stupid, , hard make white rectangle distance line. there way without tons of if() ?

im using vs2012, wpf/c# .

you can use adorners show shape "selected", way can make "selected" state visual hint in xaml.

and can use attached property "add" isselected property (boolean example) object , toggle value each time there click event rised.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
