BORDER PROCESSING IN WAVELET TRANSFORM

Geng Zexun; Qian Zengbo(Zhengzhou Institute of surveying&Mapping,450052)  
Wavelet Transform(WT)Is a very efficient signal processing method.In WT,often one requires original data Exact Reconstruction(ER) in many applications.Border-Processing has an essential effect on the ER.This paper provides two general border-precessing methods in WT,and proves that original data can be exactly reconstructed by using these methods.The experiment results also verify above conclusion.
