I have to analyze images that are distorted because the 
optical axis is not perpendicular to the plane being 
imaged. Therefore, lines that are parallel in the real 
world are not parallel in the image and rectangular objects 
appear as parallelograms. How can I correct for this?

Is the any Matlab function that calculates the images that 
would have been taken perpendicular to the plane to be 
imaged?
