This proposed scheme reversibly embeds data into image predictionerrors by using histogram-pair method with the following four thresholds for optimal performance: embedding threshold, fluctuation threshold, leftand right-histogram shrinking thresholds. The embedding threshold is used to select only those prediction-errors, whose magnitude does not exceed this threshold, for possible reversible ...

This paper proposes a geodesic-distance-based feature that encodes global information for improved video segmentation algorithms. The feature is a joint histogram of intensity and geodesic distances, where the geodesic distances are computed as the shortest paths between superpixels via their boundaries. We also incorporate adaptive voting weights and spatial pyramid configurations to include s...

Most of the natural textures are non-homogenous and stochastic by nature. In many cases these textures are also directional. In this paper we present a method for the retrieval of the non-homogenous directional textures. This method is directional histogram and it represents the directional distribution of the texture. The histogram can be formed using either directional filtering method or Hou...

UNLABELLED Cardiac resynchronization therapy (CRT) is now a well-recognized therapeutic option for patients with end-stage heart failure. However, not all patients respond to CRT, and, therefore, preimplantation identification of responders is desirable. The aim of the present study was to investigate whether the degree of left ventricular (LV) dyssynchrony, as assessed with phase analysis from...

Neutron energy-dependent angular distributions were observed for individual $\gamma$-rays from the 0.74 eV p-wave resonance of $^{139}$La+$n$ to several lower excited states $^{140}$La. The $\gamma$-ray signals analyzed in a two dimensional histogram energy, measured with distributed germanium detectors, and neutron determined time-of-flight pulsed neutrons, identify energy dependence distribut...

This paper discusses the viability of a BIST implementation for the sinusoidal histogram technique classically used for ADC testing. An original approach based on (i) approximations to estimate the ADC parameters, (ii) decomposition of the global test in a code-after-code test procedure and (iii) piece-wise approximation to compute the ideal histogram is developed. These three features allow a ...

We propose a new Monte Carlo technique in which the de-generacy of energy states is obtained with a Markovian process analogous to that of Metropolis used currently in canonical simulations. The obtained histograms are much broader than those of the canonical histogram technique studied by Ferrenberg and Swendsen. Thus we can reliably reconstruct ther-modynamic functions over a much larger temp...

We describe two methods that aim at normalizing acoustic vectors at the filterbank level such that the test data distribution matches the training data distribution. They enhance the histogram normalization technique proposed earlier by taking care of the variable silence fraction for each speaker, and by rotating the feature space. We report a number of recognition tests under minor (different...
