#Here's my code
#it works for one frame when I did 'plot(diff(test))' but I need a way to implement it to the whole images
imshow(M(:,:,1))
[x ,y]= ginput(2);
dif = zeros(size(M,3),1);
for i = 1:size(M,3)
I = M(:,:,i);
n = ceil(norm([diff(x), diff(y)]));
test = improfile(I,linspace(x(1), x(2),n), linspace(y(1), y(2),n));
end
dif(i) = diff(test);
