This paper presents a new algorithm for reducing quantization artifacts in transform coded images. For transform coded signals, we analytically show that one can determine linear ...
We provide an amplitude-phase representation of the dual-tree complex wavelet transform by extending the fixed quadrature relationship of the dual-tree wavelets to arbitrary phas...
— This paper presents a novel 3-D direction aligned wavelet transform for scalable video coding. A new generalized 3D directional threading technique is seamlessly incorporated i...
The recently completed MLIS DicoPro project addressed the need for a uniform, platformindependent interface for accessing multiple dictionaries and other lexical resources via the...

Abstract—In this paper we study the problem of evaluating the reconstruction distortion in the wavelet domain when adaptive lifting schemes (ALS) are used for the direct and inve...
