We present PRISMA’s Video Copy Detection system (P-VCD). The system is based on visual-only global descriptors, weighted combinations of distances, a pivotbased index structure, and a novel approximated search and voting algorithm for copy localization. We submitted four Runs to TRECVID 2010 CCD task: PRISMA.m.balanced.ehdNgryhst: a combination of edge histogram and gray histogram. PRISMA.m.bal...

A five-class density histogram with an index named cumulative density was proposed to analyze the short-term HRV. 150 subjects participated in the test, falling into three groups with equal numbers -the healthy young group (Young), the healthy old group (Old), and the group of patients with congestive heart failure (CHF). Results of multiple comparisons showed a significant differences of the c...

In this paper, a new method based on the class-based histogram equalization to compensate the acoustic mismatch between training and test conditions of speech recognizers is proposed. The proposed method improves the speech recognition accuracy in noisy environments by reducing two limitations of the conventional histogram equalization: The discrepancy of phonetic class distributions between tr...

Abslroa In this paper, we present B new statistical analysis method of phase resolved partial discharge (PD) measurements for the quality assessment o f the electrical insulation in high voltage machinery. The method is based on P supervised classification approach which utilizes histogram similarily analysis. The motivntian for choosing histogram similarily analysis is huofold: F i r s t the p...

This paper examines the fit of three different statistical distributions to the returns of the S&P 500 Index from 1950-2005. The normal distribution is a poor fit to the daily percentage returns of the S&P 500. The lognormal distribution is a poor fit to single period continuously compounded returns for the S&P 500, which means that future prices are not lognormally distributed. However, sums o...

OBJECTIVE The purpose of this study was to investigate the additional value of whole-lesion histogram apparent diffusion coefficient (ADC) metrics, when combined with standard pathologic features, in prediction of biochemical recurrence (BCR) after radical prostatectomy for prostate cancer. MATERIALS AND METHODS The study included 193 patients (mean age, 61 ± 7 years) who underwent 3-T MRI wi...

\Propagation, infection, and execution analysis" (termed PIE) is used for predicting where faults can more easily hide in software. To make such predictions, programs are dynamically executed with test cases. In this paper, we collect information concerning those test cases into a histogram. Each bin in a histogram represents a single test case. The score in a bin predicts the likelihood that t...

BACKGROUND The characteristics of atrial electrograms associated with atrial fibrillation (AF) termination are controversial. We investigated the electrogram characteristics that indicate procedural AF termination during continuous complex fractionated electrogram ablation. METHODS AND RESULTS Fifty-two consecutive patients with persistent AF (47 men; aged 54 ± 9 years), who underwent electro...
