Claim One:
1. A system for generating an integrated image of a fingerprint present on a curved surface of an object, the system comprising: an imaging assembly including a light source and an image capturing device, the imaging assembly enabling selective illumination of the fingerprint on the curved surface of the object to selectively create specular reflections of different aspects of the fingerprint for capture by the image capturing device; a memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: receive first image information corresponding to a first image captured by the image capturing device, the first image information including pixel values for pixels of the captured first image, and wherein a first representation of the fingerprint appears within a first set of pixels of the captured first image, and the captured first image includes data representing a specular reflection from a first aspect of the fingerprint; receive second image information corresponding to a second image captured by the image capturing device, the second image information including pixel values for pixels of the captured second image, and wherein a second representation of the fingerprint appears within a second set of pixels of the captured second image, and the captured second image includes data representing a specular reflection from a second aspect of the fingerprint, the second aspect of the fingerprint being different than the first aspect of the fingerprint, and the second set of pixels of the captured second image occupying substantially a same region of the captured second image as the first set of pixels occupies in the captured first image; compare a first plurality of pixel values from the first set of pixels with a corresponding second plurality of pixel values from the second set of pixels; determine, for each compared pixel, whether a selected pixel from the first set of pixels or a corresponding pixel from the second set of pixels has a higher pixel value; and for each compared pixel, store in a pixel value set the pixel value of the selected pixel from the first set of pixels if the selected pixel has a higher pixel value than the corresponding pixel from the second set of pixels, and store in the pixel value set the pixel value of the corresponding pixel from the second set of pixels if the corresponding pixel has a higher pixel value than the selected pixel from the first set of pixels, wherein the pixel value set provides an integrated image of the fingerprint formed from detail obtained in the specular reflection from the first aspect of the fingerprint and the specular reflection from the second aspect of the fingerprint.
