Introduction: Respiratory motion compensation in coronary artery MRI is challenging. Commonly, a pencil-beam navigator positioned on the right hemidiaphragm is used with a fixed slice tracking factor of 0.6 [1]. However, this scale factor varies among different patients [2, 3]. Respiratory selfgated navigator techniques have been introduced to directly measure the respiratory induced motion of ...

We investigate toy models for spatial and temporal instabilities in collective neutrino oscillations induced by self-interactions, with special emphasis on inhomogeneous systems densities following a profile. Simulations are based mathematica program that solves the Liouville equation or without vacuum terms, refractive terms from background medium, neutrino-neutrino forward scattering, one spa...

This paper reports the results of a study on a first sight decision tree algorithm for cursive script recognition based on the use of histogram as a projection profile technique. A postal code image data scanned is converted in a 2-dimension matrix representation to be used with a set of algorithms to provide full range segmentation. The results, based on this approach, are quite satisfactory f...

Algorithms that estimate the angle at which a document image is rotated (called a document’s skew) are surveyed. Four broad classes of technique are identified. These include methods that calculate skew from a horizontal projection profile, a distribution of feature locations, a Hough transform, or the distribution of responses from local, directionally sensitive masks. The basic method used by...

In this paper we propose a new technique for feature extraction/selection based on the projection of sensor features in class space and taking into account the sensor variance. The proposed technique is inspired by the organization of the early stages in the biological olfactory system, and proves to be highly suitable for high-dimensional feature vectors with small number of training samples. ...

We imaged nanoscale lattice strain in a multilayer semiconductor device prototype with a new X-ray technique, nanofocused Bragg projection ptychography. Applying this technique to the epitaxial stressor layer of a SiGe-on-SOI structure, we measured the internal lattice behavior in a targeted region of a single device and demonstrated that its internal strain profile consisted of two competing l...

The radiographic image is the bidimensional projection of a tridimensional volume. Interpretation of such an image is sometimes uneasy as we cannot determine ot which level the shadows are located. To dissociate the superimposed shadows, the radiologist may rely on different techniques including fluoroscopy, profile view, radiosteoroscopy, conventional tomography, transverse axial tomography or...

A streamwise constant projection of the Navier Stokes equations forced by small-amplitude Gaussian noise is simulated. It is found that this model captures salient features of fully developed turbulent plane Couette flow. In particular, the nonlinearity in the model captures the mathematical mechanism that results in the characteristic shape of the turbulent velocity profile. Further, using Tay...

In this paper a new robust and efficient algorithm to automatic text extraction from colored book and journal cover sheets is proposed. First, we perform wavelet transform. Next for edge detecting from detail wavelet coefficient, we use dynamic threshold. By blurring approximate coefficients with alternative heuristic thresholding, achieve effective edge,. Afterward, with ROI technique get bina...
