Interparticle interactions with multiple length scales play a pivotal role in the formation and stability of quasicrystals. Choosing minimal set to stabilize given quasicrystal is challenging problem. To address this challenge, we propose symmetry-preserving screening method (SPSM) design Landau theory number scales—referred as theory—that includes only essential necessary Based on generalized multiple-length-scale theory, SPSM first evaluates various spectral configurations candidate...

In this paper, a robust algorithm of digital image watermarking based on discrete wavelet transform is introduced. It adds binary watermark into gray and the host required for detecting. The have two characteristics: (1) adapted to various images owing using mean value selected coefficients. (2) Arnold pretreatment eliminates spatial correlation disperses error bits among all pixels make more strongly against cropping operation. Experiment results show that proposed invisible common processing

Detection of the visual salient regions is a challenging and significant problem in computer vision. In this paper, we propose boundary based prior map soft-segmentation convex hull to improve saliency detection. First, present utilize information obtain coarse map. Then improved by proposed form observation likelihood Finally, Bayes formula applied combine these two maps. Experiments on publicly available database show that our augmented framework performs favorably against state-of-the-art...

Generating emotional responses is crucial for building human-like dialogue systems. However, existing studies have focused only on generating by controlling the agents' emotions, while feelings of users, which are ultimate concern a system, been neglected. In this paper, we propose novel variational model named EmoElicitor to generate appropriate that can elicit user's specific emotion. We incorporate next-round utterance after response into posterior network enrich context, and decompose...

This letter presents a novel superpixel based graph cuts algorithm for human body segmentation from images. The standard constructs the t-links and n-links separately. While in this letter, we argue that construction of these two links can be build simultaneously. proposed starts complete similarity on superpixels where have been embedded hence easily obtained using max pooling function distance matrix respectively. strategy not only makes more accurate but also method robust to selection...

In order to investigate the mechanism of uranium accumulation in Kupferschiefer, 88 samples from 10 sections were analysed by geochemical method. The results indicate that higher contents originated and are transported underlying Rotliegendes into Kupferschiefer oxidized brines, then precipitated when they encountered organic matter, which occurred as reductant, Kupferschiefer.

In this paper, we propose a novel and integrated framework to estimate human pose. Firstly, pose cluster of the relative location between connected parts is applied before pictorial structure modeling, which can make each model more faithful whole estimation flexible various kinds poses. And then, different from previous single global model, mixture models based on clusters obtain candidates. Furthermore, overcome double-counting problem, also present constraint function recombine candidates...
