In this paper, we describe an improved method of personal positioning and orientation using image registration between input video frames and panoramic images captured beforehand. In our previous work, we proposed the method of image registration with an a ne transform. However, the a ne transform is generally not capable of image registration between a frame and a panorama. We improved the pre...

In their randomised trial of treatments for patients with chonic fatigue syndrome, Peter White and colleagues (March 5, p 823) defi ne a clinically useful diff erence between the means of the primary outcomes as “0·5 of the SD of these measures at baseline, equating to 2 points for Chalder fatigue questionnaire and 8 points for short form-36”. They cite achieving a mean clinically useful differ...

Fast and accurate estimation of soft error rate in VLSI circuits is an essential step in a soft error tolerant ASIC design. In order to have a cost e®ective protection against radiation e®ects in combinational logics, an accurate and fast method for identi ̄cation of most susceptive gates and paths is needed. In this paper, an e±cient, fast and accurate method for soft error propagation probabil...

There are few methods which easily measure the shape of transparent objects easily In this paper we propose a method to estimate the surface shape of transparent objects by analyzing the polarization state of the light Previous methods do not provide enough accuracy because of the lack of deeply analyzing the light re ected refracted and transmitted inside the transparent object Proposed method...

A new technique for description and recognition of human gestures is presented. First, a method is proposed to represent gestures as an ordered sequence of simple basic motions. It is based on the rate of change of gesture motion direction (referred to as \curvature") that is estimated using optical ow from monocular motion images. Then, proceedings from the method, a real-time gesture recognit...

Background Noninvasive ventilation (NIV) (continuous positive airway pressure [CPAP] or noninvasive intermittent positivepressure ventilation [NIPPV]) appears to be of benefi t in the immediate treatment of patients with acute c...

The results presented in this paper are part of a research project to investigate the possibilities to apply massively parallel architectures for numerical weather forecasting. Within numerical weather forecasting several numerical techniques are used to solve the model equations. This paper compares the performance of implementations on a MasPar system of two techniques, nite di erence and spe...

An important di erence in inductive bias between machine learning approaches is whether they assume the e ects of di erent properties on a target variable to be cumulative or not. We believe this di erence may have an important in uence on the performance of machine learning or data mining techniques, and hence should be taken into account when deciding which techniques to use. We illustrate th...

We present a general methodology for indexing with multivariate features based on the Bhattacharyya distance, which takes into account both the mean-di erence and the covariancedi erence between two distributions. To reduce the amount of computations and the size of logical database entry, we approximate the Bhattacharyya distance in the low dimensional subspace of the rst few principal compone...
