摘要：
The information in zero crossings (ZC) of images is investigated. B. F. Logan's conditions (Bell Lab. Tech. J. , pp. 261-285 and 287-306, Feb. 1984), specifying when a one-dimensional signal may be recovered (within a multiplicative constant) from its ZC, are extended for various cases of two-dimensional signals. An algorithm is implemented in the reconstruction of context-free bandpass images. It is also applied in the reconstruction of contextual images after dissecting the image into appropriate bandpass band-limited two-dimensional signals. In almost all cases for which the spectrum is confined to less than an octave in one dimension, the reconstruction algorithm converges, whereas it does not converge for any signal exceeding one octave in bandwidth. The proposition that images are well represented by the partial information confined to ZC is substantial.
