1. A computer-implemented method, comprising: automatically selecting a particular profile for a set of distorted component images from among a plurality of profiles according to metadata corresponding to the set of distorted component images, wherein each of the plurality of profiles stores information for a particular camera/lens combination including corresponding pre-calculated unwarping functions each operable to detect feature points in individual images associated with a corresponding camera/lens combination, match detected feature points one to another to establish feature correspondences between the individual images, and generate substantially rectilinear feature point coordinates for unwarping according to the matching; determining a pre-calculated unwarping function for the set of distorted component images that is stored in the particular profile; and applying the pre-calculated unwarping function to generate a composite image from the set of distorted component images by joining the distorted component images one to another using the rectilinear feature point coordinates generated using the pre-calculated unwarping function.
