i need code or function in matlab to convert color image to gray and convert gray to binary first employ Canny edge detection with binary thresholding on the original image to keep the most signicant edges only, which reliably represent foot contours.and next step morphological dilation using a square structuring element to close the boundary.Last, we employ morphological erosion on this image.....thanks

What was wrong with the answer I gave you in your duplicate question? http://www.mathworks.com/matlabcentral/answers/160818#answer_157274
Why simply just ask again?

It found the boundary. Not sure why it matters how it was done. Sure you could use something that's not as good and then try a bunch of things to fix it up, but why, when there's a simpler and better way. I never would have looked at that image and said "Let's use edge detection."

clear
clc
close all;
img_file = 'put your image here';
img_wk = imread(img_file);
figure(1), imshow(img_wk);
img_wk_gs = rgb2gray(img_wk); %converts color image to grayscale
figure(2), imshow(img_wk_gs);
img_wk_gs_edge = edge(img_wk_gs,'canny');
figure(3), imshow(img_wk_gs_edge);
img_wk_gs_edge_sobel = edge(img_wk_gs,'sobel');
figure(4), imshow(img_wk_gs_edge_sobel);
img_wk_bw = im2bw(img_wk, 0.7); %converts to black and white binary image
figure(5), imshow(img_wk_bw);
