In this paper, we develop the nonsubsampled contourlet transform (NSCT) and study its
applications. The construction proposed in this paper is based on a nonsubsampled …

In this paper, a novel unsupervised change detection method called adaptive Contourlet
fusion clustering based on adaptive Contourlet fusion and fast non-local clustering is …

This paper proposes a directional design method of 2-D nonseparable linear-phase
paraunitary filter banks. The proposed method is based on a lattice structure consisting of …

In this paper, we propose a new method for the construction of multi-dimensional, wavelet-
like families of affine frames, commonly referred to as framelets, with specific directional …

Modern medical diagnosis equipments included with digital signal processing capabilities
have been used for fast and accurate diagnosis of brain structure abnormalities. In this …

Recent studies show that hybrid panchromatic sharpening (pan-sharpening) methods using
the non-sub-sampled contourlet transform (NSCT) and classical pan-sharpening methods …

This paper proposes a boundary operation technique of 2-D nonseparable linear-phase
paraunitary filter banks (NS-LPPUFBs) for size limitation. The proposed technique is based …

This letter extends the formulation developed by Sherlock and Monro for parameterization of
orthonormal wavelet filter banks. Additional constraints are proposed to ensure that the …

In this paper, we use the ideas presented in [1] to construct application-targeted
convolutional neural network architectures (CNN). Specifically, we design frame filter banks …

Face recognition technology is widely used in the field of public security. To improve the
recognition accuracy under non-ideal lighting conditions, a face recognition method with …
