One of the many ways to do this:
I = imread('http://imageshack.us/a/img401/5148/0mbt.jpg');
J = I == 255; % note that there are many '255' valued pixels near the intersection.
se = strel('disk',5);
K = imerode(J,se); % remove some of the unwanted noise pixels.
[x y] = find(K) %returns the x,y coordinates of the region in question.
