A study on multi-scale DEM representation and topographic feature line extraction

Lifting scheme is a new wavelet transformation method, which is more effective than the multi-resolution analysis of wavelet theory. This paper presents the fundamentals and the three constructing steps of lifting scheme briefly. And it uses lifting method to process DEM data with multi-scale repres...
