Complex ridgelets for the extraction of morphological features on engineering surfaces
, 2005 In this paper, a complex ridgelets transform, which provides approximate shift invariance analysis of line singularities, is proposed to extract morphological features with linear or directional/objective property, by taking a Dual Tree Complex Wavelet ...

3-D Discrete Analytical Ridgelet Transform [PDF]
IEEE Transactions on Image Processing, 2006 In this paper, we propose an implementation of the 3-D Ridgelet transform: the 3-D discrete analytical Ridgelet transform (3-D DART). This transform uses the Fourier strategy for the computation of the associated 3-D discrete Radon transform. The innovative step is the definition of a discrete 3-D transform with the discrete analytical geometry theory ...

Intensity estimation of non-homogeneous Poisson processes from shifted trajectories [PDF]
, 2013 In this paper, we consider the problem of estimating nonparametrically a mean pattern intensity λ from the observation of n independent and non-homogeneous Poisson processes N1,…,Nn on the interval [0,1].

Tight Frames of k-Plane Ridgelets and the Problem of Representing Objects Which Are Smooth Away from d-Dimensional Singularities in R^n [PDF]
, 2007 For each pair (n, k) with 1 # k < n, we construct a tight frame (# # : # # #) for L 2 (R n ), which we call a frame of k-plane ridgelets. The intent is to efficiently represent functions which are smooth away from singularities along k-planes ...

Directional edge and texture representations for image processing [PDF]
, 2007 An efficient representation for natural images is of fundamental importance in image processing and analysis. The commonly used separable transforms such as wavelets axe not best suited for images due to their inability to exploit directional ...

Face recognition based on ridgelet transforms
Procedia Computer Science, 2010 AbstractThis paper relates to a face recognition and verification technique based on ridgelet transforms. Our proposed method first uses the ridgelet transform of the face image for feature extraction. This involves first applying a sequen- tial combination of radon and wavelet transforms to both the training and test images.
