摘要：

The purpose of this investigation was to examine the use of four image features in describing digitized radiographic bony scan lines, or profiles. These features include the mean pixel intensity, I (x); pixel intensity variance, var I (x); mean absolute Fourier transform coefficient, \F(u)\; and mean spatial first moment of the absolute Fourier coefficients, M1. In an animal model I (x) and M1 differed significantly while \F (u)\ tended to differ significantly between digitized radiographic profiles of osteoporotic (n = 6) and control (n = 6) rabbit humeri. Case examples illustrating the application of this technique to digitized radiographs of human interproximal alveolar bone are presented.
