In this paper we presented a new wavelet packet transform method based on local deviation.Wavelet packet transform decomposed an image into low frequency hand and high frequency hand in different level;local window and local sub-window statistic in the wavelet domain were used to further classify the wavelet coefficients into the edge and non-edge coefficients.In the fusion processing
the fused approximate coefficients were obtained by average method
the fused detailed coefficients were obtained by several ...
