Answer 1

What about this;

a) convert to binary just to make the algorithm faster.

b) Perform a find on the resulting array

c) choose the element which has either lowest/highest row/column index (you would have four points to choose from then

d) now keep searching neighbours

• have a global criteria for search that if search does not result in more than a few iterations, the point selected is false and choose another extreme point

e) going along the neighbouring points, you will end up at a point where you have three possible neighbours.That is you intersection
