REad about imdistline; this will allow you to calculate the distance between the points interactively. For this you are supposed to have image toolbox. 
[y,x] = find(I==1) ;  % give the pixel value
The above line, gives you the coordinates/ points of the required pixel. YOu have the points in hand, you can do the process needed.
