Hi everyone,

At my this project i am going to make edge detection. I will use matlab’s built in functions.

This is my original photo. I will read it, convert to the gray, finally from the gray photo i will detect the edges.  As you can see from the code below, i used sobel edge detection.

lena=imread('lena.jpg');
lena_gray=rgb2gray(lena);
lena_gray_double=double(lena_gray);
lena_gray_double=lena_gray_double/max(max(lena_gray_double));
figure;
edge(lena_gray_double,'sobel')
title('Built-in Edge Detected Image With Sobel');
