The bilateral wavelet pyramid (BWP): A novel image representation
Chao Wang, Lifeng Sun, Zhuoyuan Chen, Jianwei Zhang, Shiqiang Yang · 2009
In this paper, we study the properties of the bilateral pyramid, based on which a novel image representation-the bilateral wavelet pyramid (BWP) is proposed. The BWP provides a multiresolution technique to manipulate image variances simultaneously in radiometric, spatial and frequency domains. Application to texture retrieval is discussed to demonstrate the effectiveness of the BWP.
