data=imbinarize(imread('image.jpeg'));
result=edge(data);
figure,imshow(result);
[r,c]=find(result==1);
figure,plot(c,r,'.');

I found the source of the problem. The reason is that the MATLAB software draws the line with the point in the upper left corner as the origin, so we see the image in the opposite direction to the original image.
