MATLAB: Welcom i need help

duplicate postimage processingImage Processing Toolbox

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?

I suggest you grab a book on image processing and look up morphological operations.

Opening is an erosion followed by a dilation.

Similarly closing is a dilation followed by an erosion.

MATLAB: How to produce edge detected image

 I = imread('circuit.tif');
 BW1 = edge(I,'prewitt');
 BW2 = edge(I,'canny');
 BW3 = edge(I,'sobel');
 figure, imshow(BW1)
 figure, imshow(BW2)
 figure, imshow(BW3)

Or you can choose manual threshold like,

 BW1 = edge(I,'prewitt',0.4);
 BW2 = edge(I,'canny',0.4);
 BW3 = edge(I,'sobel',0.4);
 figure, imshow(BW1)
 figure, imshow(BW2)
 figure, imshow(BW3)
