Hello Hasan,
You can use the function 'imcontour' to observe and compare the contours of the two images. But, before that, you might want to sharpen the image using unsharp masking or laplacian. For which, you may use the function 'imsharpen'. The code may look something like this:
i=imread('Capture1.png');
i=rgb2gray(i);
i_s=imsharpen(i); %unsharp masking
i_s_h=histeq(i_s);
imcontour(i_s_h,3);
Hope this helps.
