1. A method for testing image pipelines, the method comprising: transforming an untransformed captured image multiple times using a plurality of pipelines, thereby generating a plurality of transformed images; comparing a functional set of metrics associated with each of the plurality of transformed images with a functional set of metrics associated with each image in a ground truth set; and from the comparison, determining which of the plurality of pipelines generates a transformed image that is functionally closest to an image in the ground truth set.
