| Abstract: | The construction of true bidimensional wavelet is studied in this paper.According to nonseparable autocorrelation function and spectral density model of bidimensional image,the optimal interpolators are proposed.Using the interpolators as predictor and updater,by the lifting scheme,a set of optimal-impolating true bidimensional wavelets is constructed in this paper.The experimental results on MSE and energy entropy show that the proposed FBs perform better than the well-know Neville FBs on interpolating and... |
