Themultidelay block frequency-domain (MDF) adaptive filter is an excellent candidate for both acoustic and network echo cancellation. There is a need for a very good double-talk detector (DTD) to be combined efficiently with the MDF algorithm. Recently, a DTD based on a normalized cross-correlation vector was proposed and it was shown that this DTD performsmuch better than the Geigel algorithm ...

We examine the validity of two methods for estimating glacier equilibrium-line altitudes (ELAs) from topographic maps. The ELA determined by contour inflection (the kinematic ELA) and the mean elevation of the glacier correlate extremely well with the ELA determined from mass-balance data (observed ELA). However, the range in glacier elevations above sea level is much larger than the variation ...

Estimation of assortative mixing by degree in networks is important because it points to the existence of a hub-like core in networks with scaling degree distributions. Such networks show self-similarity and other emergent properties of complex networks. Degree correlation has generally been used to measure assortative mixing of a network. But it has been shown that degree correlation cannot al...

Perplexity(per word) is the most widely used metric for evaluating language models. This is mostly due to a its ease of computation, lack of dependence on external tools like speech recognition pipeline and a good theoretical justification for why it should work. Despite this, there has been no dearth of criticism for this metric. Most of this criticism center around lack of correlation with ex...

There have been many investigations into the factors that underlie variations in individual student performance in college physics courses. Numerous studies report a positive correlation between students’ mathematical skills and their exam grades in college physics. However, few studies have examined students’ learning gain resulting from physics instruction, particularly with regard to qualita...

In this paper, the Normalized Correlation based Quantization Index Modulation (NCQIM), Least Significant Bit (LSB) and Code Division Multiple Access (CDMA) techniques are combined for reversible watermarking. By using this method, the normalized correlation is calculated between the host signal and a random signal. Then the modulation is performed on generated normalized correlation by using co...

Landslide monitoring is important for geological disaster prevention, where Synthetic Aperture Radar (SAR) images have been widely used. Compared with the Interferometric SAR (InSAR) technique, intensity-based offset tracking methods (e.g., Normalized Cross-Correlation method) can overcome the limitation of InSAR’s maximum detectable displacement. The normalized cross-correlation (NCC) method, ...

BACKGROUND To assess whether CT-derived texture features predict survival in patients undergoing resection for pancreatic ductal adenocarcinoma (PDAC). METHODS Thirty patients with pre-operative CT from 2007 to 2012 for PDAC were included. Tumor size and five texture features namely uniformity, entropy, dissimilarity, correlation, and inverse difference normalized were calculated. Mann-Whitne...

This paper proposes optimized Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) watermarking technique using multi-objective evolutionary algorithm using Fibonacci-Lucas transform. In any image watermarking technique, there is always challenge for researcher to achieve perceptual quality and robustness simultaneously under high payload scenario because these two quality me...
