i am working on project of edge detection and i am using fuzzy logic the problem i am facing is that i want to detect the without using rgb colour code ,means i want to detect the edge and also i want that the color of the image also appear in output

Igray = 0.2989*Irgb(:,:,1)+0.5870*Irgb(:,:,2)+0.1140*Irgb(:,:,3);

figure image(Igray,'CDataMapping','scaled'); colormap('gray') title('Input Image in Grayscale') I = double(Igray); classType = class(Igray);

Try the edge() function on the gray scale image.

i have already done this but it is not working

Call the Mathworks. The edge() function should definitely work. Does it throw an error when you call it, like it says there is no such function? Tech support can help you reinstall and walk you through a simple example to make sure that edge() works, and that you have a license to use the Image Processing Toolbox. What does this say

>> which -all edge

It will show if you have some other m-file, like one you wrote, that is causing the built-in edge() function to not work.

I=rgb2gray(i); BW1 = edge(I,'canny'); sir in this code as rgb2gray will convert the image into 2d and it will convert the coloured image into gray scale but sir i want the edge to be detected and also in my output contains the colour in the image. i have attached an image in this i want the edge detected and i also want that my output shows the colour in particular band of a given image
