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.

x 17235x1 double min 1 and max 1024
y 17235x1 double min 1 and max 1024
x and y are showing the 17235 horizontal line and 1 vertical line how do i know the intercept point ?
Could you make me clear ?

Do we write a program such a way that virtual lines can be drawn on both the x and y white line of the above image

From that virtual line we can find out the intercept where they cross each other
