Hi
I have image displayed using imshow().
I want to get image x,y coordinates on the location where the mouse points, not clicked.
For example if mouse cursor is on pixel(230,120),then i want to get this position as output.
Urgent help needed guyz.

Go in to the Matlab interactive documentation and search for CurrentPoint

I don't know off-hand; I haven't had a need for that. I know it has been 
discussed here a few times before.

One approach would be to use a WindowButtonMotionFcn callback on the 
figure, and each time the cursor was moved, store the current point in 
some location. When you want to know where you are, retrieve the current 
contents of that location. You might have to adjust for differences 
between figure coordinates and axes coordinates.
