this is my image on which the machine will move .. now i want that matlab controls the arduino through which the machine is connected.

[Walter Roberson]

Image is missing.

[khushboo chhikara]

this is the image.

[Walter Roberson]

So what is the path?

I would tend to think that jumping between the center and the small parts at the bottom would not be efficient, but it could be necessary if the CNC is restricted to moving only in one direction on a particular axes.

[khushboo chhikara]

not on the small parts at the bottom .. only the main line will be followed. But i dont know how to do that with matlab and arduino.

Have you done an imclose() then bwskel(), possibly followed by spur removal from bwmorph ?

clc,clear,close all;
% cam = webcam('HD Webcam C615')
% im1 = snapshot(cam);
% % set(handles.axes1,'Visible','on');
% % axes(handles.axes1)
im=rgb2gray(im1);
figure,imshow(im);
clear('cam')
% im = rgb2gray(imread('white_3.jpg'));
H = fspecial('Gaussian',[2 2],15);
im = imfilter(im,H);
imshow(im);title('Original image'); 
sim = edge(im, 'sobel');
se = strel('disk', 2);
sim = imdilate(sim, se);
sim = bwareaopen(sim, 50);
sim = imerode(sim, se);

imshow(sim);title('after Sobel');
 h = waitbar(0,'Sewing....');

[B,L] = bwboundaries(sim,'noholes');
imshow(label2rgb(L, @jet, [.5 .5 .5]))
imwrite(L,'new.jpg')
hold on
for k = 1:length(B)
   boundary = B{k};
   h1=plot(boundary(:,2), boundary(:,1), 'w', 'LineWidth',0.5)
          waitbar((.5+(k/length(B))/2),h);

end
