Lifting Scheme and Its Application to Edge Detection
摘要
Lifting scheme is a useful and very general technique for constructing wavelet decomposition. The paper adapts the lifting into redundant lifting to obtain shift invariant wavelet transform. In prediction and update stages of the lifting morphological operator is adopted for preserving local maxima of a signal over several scales, which is particularly useful in wavelet-based signal detection. The new transform presented in the paper is applied in multiresolution edge detection of medical image and experiment results are given to show better performance and applicable potentiality.
