Many camera systems are dedicated to the capture of bi-level objects, including documents, bar codes, handwritten signatures, and vehicle license plates. Degradations in the imaging systems, however, cause blurring to the output images and introduce many more intensity levels. The blurring often arises from the optical aberrations and motions between the… (More)
