YourImage = imresize(imread('baby.jpg'), 1/8);
R = YourImage(:,:,1);
G = YourImage(:,:,2);
B = YourImage(:,:,3);
ER = edge(R, 'canny');
EG = edge(G, 'canny');
EB = edge(B, 'canny');
anyedge = ER | EG | EB;
alledge = ER & EG & EB;
majorityedge = (ER + EG + EB) >= 2;
Rany = R; Rany(anyedge) = 255;
Gany = G; Gany(anyedge) = 0;
Bany = B; Bany(anyedge) = 0;
RGBany = cat(3, Rany, Gany, Bany);
Rall = R; Rall(alledge) = 255;
Gall = G; Gall(alledge) = 0;
Ball = B; Ball(alledge) = 0;
RGBall = cat(3, Rall, Gall, Ball);
subplot(3,2,1)
imshow(YourImage);
title('Original');
subplot(3,2,2);
imshow(anyedge)
title('Edge found in any plane');
subplot(3,2,3)
imshow(majorityedge)
title('Edge found in 2+ planes');
subplot(3,2,4)
imshow(alledge)
title('Edge found in all planes');
subplot(3,2,5)
imshow(RGBany)
title('Original outlined with any edge');
subplot(3,2,6)
imshow(RGBall)
title('Original outlined with all edge')
Bany = B; Bany(anyedge) = 0;

i want to convert RGB image to R , G and B
after that convert R to canny edge
after that convert G to canny edge
after that convert B to canny edge
after that sum three pic
i mean
i have image i want firstly split this image into R , G and B and show 3 images red , green and blue images
secondly apply edge canny in each 3 colore image
canny edge detection on green image (g_d)
canny edge detection on blue image (b_d)
canny edge detection on red image (r_d)
after that add (g_d)+(b_d)+(r_d) to have colore canny detection
