Unformatted text preview: Lifting Scheme: Wavelets were defined as translates and dilates of one mother wavelet function and were used to analyze and represent a general function. Several techniques exist to construct wavelet bases and one of those techniques is lifting scheme. It provides a simple method for custom designing biorthogonal wavelets. It characterizes all possible sets of biorthogonal filters having the H filter. Suppose { , , , } H H G G form a set of biorthogonal filters. The perfect reconstruction condition for the biorthogonal case are given by * * * * ( ) ( ) ( ) ( ) I 1 ( ) ( ) ( ) ( ) H G H H H G G G * * * * ( ) ( ) ( ) ( ) I 2 ( ) ( ) ( ) ( ) H G H H H G G G The filter responses are related as...
