The normal distributions transform (NDT) is an effective paradigm for point set registration. This method was initially designed pair-wise registration and suffers from the accumulated error problem when directly applied to multi-view Under framework of point-to-cluster correspondence, this paper proposes a novel named 3D based on (3DMNDT), which integrates k-means clustering Lie algebra optimi...

introduction: the aim of this study was to evaluate the impact of measurement of coronary artery calcification score (cac) in patients with suspected coronary artery disease (cad) and a normal myocardial perfusion scan. methods: in a prospective study we measured the calcium score of 74 patients (29 m, 45 f, mean age 58.7 (m) and 64.4 (f)) with suspicion of cad and a normal perfusion scan. in ...

In this paper, a writer-dependent signature verification method is proposed. Two different types of texture features, namely Wavelet and Local Quantized Patterns (LQP) features, are employed to extract two kinds of transform and statistical based information from signature images. For each writer two separate oneclass support vector machines (SVMs) corresponding to each set of LQP and Wavelet f...

The objective of current work is to show the effectiveness of using wavelet transform for detection and localization of small damages. The spatial data used here are the mode shapes and strain energy data of the damaged plate. Because the wavelet coefficients are performed with various scale indices, local perturbations in the mode shapes and strain energy data can be found in the finer scale t...

Detection of gradual transition and the elimination of disturbances caused by illumination change or fast object and camera motion are the major challenges to the current shot boundary detection techniques. These disturbances are often mistaken as shot boundaries. Therefore, it is a challenging task to develop a method that is not only insensitive to various disturbances but also sensitive enou...
