ABSTRACT:
A method of making and using a target to verify an image from an imaging device is provided. A target is formed with a set of color patches that have numerically valued color characteristics. The color patches are repeated throughout the target as to permit verification of colors as a function of position of the color patches with respect to the target. A set of markers are provided to facilitate machine recognition of the target such that each position of the color patches may be referenced relative to the set of markers.
