Re: how to find intersection in image matrix and plot it

Owh sorry..find the intersection between 0 and 1..i'm guessing using command 'find'..but I dont quite understand the command..about finding non zero element..is it possible to use that ? and plot the intersection (intersection between black and white if refer to the image..so logically intersection between 0 and 1 if refer to the matrix )
Am I right ? Sorry I'm new to matlab..

Thanks.
