| Abstract: | CBMD is a computer program for digitizing the analog magnetic photographs produced by CB-3, using professional image processing techniques. Since the adjustment of analog instrument and storage condition is dissimilar, the photographs are of different status. Users should consider how to process the photographs to guarantee the digitization accuracy of magnetic photographs. In this paper, several factors that influence the process accuracy are discussed and resolutions are put forward. |
