How to find RGB image edge detection using directional operator method?

Hi, Priyanka

Generally, you can perform edge detection with edge command from Matlab.

Which operator? Sobel, prewitt, canny, or what?

I = imread('tape.png');
Igray = rgb2gray(I);

Iedge = im2uint8(edge(Igray,'canny',0.2));
Iedge = repmat(Iedge,[1 1 3]);
Ifinal = I + Iedge;    
imshow(Ifinal);

Thanks my friend.

Actually my project is A color YUV Image Edge Detection Method Based On Histogram Equalization Transformation. The main idea about this project is YUV image edge detection gives better result than RGB image edge detection. this project contains following steps

1>RGB image edge detection using

a>Directional operator method

b>component gradient operator

2>RGB to YUV color space conversion.

3>YUV image edge detection.

My project is one of the working IEEE paper.

If u know something about this plz reply me. can u give me your email address? So I can email my project paper to you.So you eaisly understand what exactly this project contains.

Gradient operators which are used here

1>Sobel gradient operator

2>Laplace gradient operator
