[rows, colm]=size(Thin_image);
% Avoid the boundary pixels
bifurcation=0;
ridge=0;
for i=2:rows-1
for j=2:colm-1
sub_matrix=(Thin_image(i-1:i+1,j-1:j+1));
if sub_matrix(2,2)==1
sub_matrix=sum(sub_matrix(:))-1;
if sub_matrix==1
P=fprintf('it is a ridge termination');
i
j
ridge=ridge+1;
else if sub_matrix==3
Q=fprintf('it is a bifurcation');
i
j
bifurcation=bifurcation+1;
end
end
end
end

Thin_image = single(rand(7) > .8); % for example
out = conv2(Thin_image,ones(3),'valid');
ridge = sum(out(:) == 1);
bifurcation = sum(out(:) == 3);
