1. A method comprising:
detecting regions of interest within a first image generated from a first physical camera (PCAM) positioned at first coordinates;
generating a second image from a virtual camera (VCAM) positioned at the first coordinates;
establishing pixel-to-pixel correspondence between the first image and the second image; and
determining a quality value for the second image by evaluating the second image in view of the first image.
