UNLABELLED The significance of left ventricular (LV) dyssynchrony for the prediction of response to cardiac resynchronization therapy (CRT) has been demonstrated. Parameters reflecting LV dyssynchrony (phase SD, histogram bandwidth) can be derived from gated myocardial perfusion SPECT (GMPS) using phase analysis. The feasibility of LV dyssynchrony assessment with phase analysis on GMPS using Qu...

This paper investigates the possibility of computerised diagnosis of malaria and describes a method to detect malaria parasites (Plasmodium spp) in images acquired from Giemsa-stained peripheral blood samples under conventional light microscopes. Prior to processing, the images are transformed to match a reference image colour characteristics. The parasite detector utilises a Bayesian pixel cla...

Information hiding has been an important research area for copyright protection in modern multimedia technologies. In this paper, a weight-based prediction scheme is presented to enhance the performance of several reversible histogram-based data hiding approaches. By computing the solution of the least-squares problem, we obtain the optimal set of weights for the neighboring pixels to improve t...

Abstract In this work, the pulsation analysis is performed on 83 high-amplitude δ Scuti stars (HADS), which have been observed by Transiting Exoplanet Survey Satellite. The results show that 49 of these HADS single-mode pulsation, 27 them radial double-modes (in 22 pulsate with fundamental and first overtone modes five second modes), seven triple-modes (three are newly confirmed triple-mode HAD...

In implement prediction-based reversible steganographic scheme based on image in painting. In this scheme the reference pixels are adaptively selected according to the distribution characteristics of the content of the image. Image in painting based on partial differential equations is used to complete the prediction process by the reference pixels. The histogram prediction error is shifted to ...

Protein structure prediction is beginning to be, at least partially, successful. Evaluating predictions, however, has many elements of subjectivity, making it difficult to determine the nature and extent of improvements that are most needed. We describe how the funnel-like nature of energy functions used for protein structure prediction determines their quality and can be quantified using lands...

In the conventional video codec, B pictures usually employ five prediction modes, including bi-prediction, direct prediction, forward prediction, backward prediction and intra modes. Among them, the direct and bi-prediction modes, whose prediction values are achieved from both forward and backward reference pictures, are more efficient in exploiting the temporal correlation between the referenc...

In this paper, we present a novel massively parallel algorithm for accelerating the decision tree building procedure on GPUs (Graphics Processing Units), which is a crucial step in Gradient Boosted Decision Tree (GBDT) and random forests training. Previous GPU based tree building algorithms are based on parallel multiscan or radix sort to find the exact tree split, and thus suffer from scalabil...

We propose a learning algorithm for nonparametric estimation and on-line prediction for general stationary ergodic sources. The idea is to prapare many histograms and estimate the probability distribution of the bins in each histogarm. We do not know a priori which histogram expresses the true distribution: if the histogram is too sharp, the estimation captures the noise too much (overestimatio...
