dear all,
when i'm calling images to be shown and write axis on, i found y axis is reversed, i mean if the image is 512x512 ,i found the (x, y) coordinates is (0,512) not (0,0) as it is supposed to be. it starts from high value to low value bottom to top.
how can i solve this problem?
thanks and best regards

Please compare "axis image" to "axis xy" in the documentation, http://www.mathworks.com/help/techdoc/ref/axis.html
