@Nupur: You are asking for trivial code. Why don't you try this by your own? Simply insert a if BW(i,j)==1.

You can still use the convolution tools:
im=randi([0 1], 315, 274);
kernel=[1 1 1;1 0 1;1 1 1];
sum_of_8=convn(im,kernel,'same');
L_bifurcation = im==1 & sum_of_8==3;
L_termination = im==1 & sum_of_8==1;
The last two variable contain the positions you are interested in.
