Header-footer carving, along with header-size carving, are by far the most common techniques for photo recovery. [citation ...
Fragile or valuable originals are protected when digital surrogates replace them, and severely damaged photographs that cannot be repaired physically are revitalized when a digital copy is made. [2] Creation of digital surrogates allows originals to be preserved. [3] However, the digitization process itself contributes to the object's wear and ...
