摘要

This paper aims at a multiscale image representation which is rotation-and shift-invariant. The wavelet energy distribution is defined, and an image recovery algorithm is proposed based on the representation. In order to derive the image representation, which is almost rotation-invariant, two or three components indifferent directions of the discrete binary wavelet transform are integrated into a wavelet energy distribution. The image is recovered from the wavelet energy distribution by iterative operations.
