Claim One:
1. A method for transforming frame coordinates in an image processing system, the method comprising: receiving image data in a first coordinate space and receiving a second coordinate space; selecting, based on a set of relative coordinate space mappings, at least a first transformation for mapping of the image data in the first coordinate space to an intermediate image canonical coordinate space, wherein the intermediate image canonical coordinate space has coordinates which are logically independent of the image processing system, wherein the first transformation is an inverse change transformation matrix and wherein the selecting includes representing relative directions from the first coordinate space to the intermediate image canonical coordinate space using at least one of a group of coordinate mappings consisting of: i) rightward, downward, ii) leftward downward, iii) leftward, upward, iv) rightward, upward, v) downward, rightward, vi) downward, leftward, vii) upward leftward, and viii) upward, rightward, at least the first transformation; selecting, based on the set of relative coordinate space mappings, at least a second transformation for mapping from the intermediate image canonical coordinate space to the second coordinate space, and wherein and the second transformation is a forward change transformation matrix and wherein the selecting includes representing relative directions from the intermediate image canonical coordinate space to a second coordinate space using at least one of a group of coordinate mappings consisting of: i) rightward, downward, ii) leftward downward, iii) leftward, upward, iv) rightward, upward, v) downward, rightward, vi) downward, leftward, vii) upward leftward, and viii) upward, rightward, at least the second transformation; and performing a transformation operation, using at least one processor and memory in the image processing system, upon the image data to transform the first coordinate space through the intermediate image canonical coordinate space to the second coordinate using at least the first transformation and the second transformation.
