Thread Subject: image processing help

Hello,

I have an image (for eg, a bone). I have found the coordinate points (x,y) on the four sides (one on each side). Now I want to crop the image such that the the coordinate points are perpendicular to adjacent points. Any ideas are welcome.

Thank you,

Mathew.

A point can't be perpendicular to anything, but it sounds like you want to first rotate the image so that your non-axis-aligned rectangle becomes axis-aligned, then crop to contain just that rectangle. Is that right? imrotate and imcrop will probably help.
