We propose a bootstrap learning algorithm for salient object detection in which both weak and strong models are exploited. First, saliency map is constructed based on image priors to generate training samples model. Second, classifier directly from an input learned detect pixels. Results multiscale maps integrated further improve the performance. Extensive experiments six benchmark datasets demonstrate that proposed performs favorably against state-of-the-art methods. Furthermore, we show...
Compared to the pristine WO<sub>3</sub>, oxygen vacancy defect levels of sub-stoichiometric WO<sub>3−X</sub> narrow bandgap and promote separation photogenerated electron–hole pairs.
We propose a salient object detection algorithm via multi-scale analysis on superpixels. First, segmentations of an input image are computed and represented by In contrast to prior work, we utilize various Gaussian smoothing parameters generate coarse or fine results, thereby facilitating the regions. At each scale, three essential cues from local contrast, integrity center bias considered within Bayesian framework. Next, compute saliency maps weighted summation normalization. The final map...
Automated detection of vascular structures is great importance in understanding the mechanism, diagnosis, and treatment many pathologies. However, automatic continues to be an open issue because difficulties posed by multiple factors, such as poor contrast, inhomogeneous backgrounds, anatomical variations, presence noise during image acquisition. In this paper, we propose a novel 2-D/3-D symmetry filter tackle these challenging issues for enhancing vessels from different imaging modalities....
Monoclinic β-Ga2O3 nanosheets hold great potential applications in electronic, optical, and photocatalytic fields. In this study, two-dimensional were successfully fabricated through a simple crystalline phase transition from the as-prepared ultrathin γ-Ga2O3 nanosheets. The hydrogen evolution reaction under UV light irradiation was achieved on two kinds of photocatalysts. However, with higher crystallinity shows lower activity comparison γ-Ga2O3. average apparent quantum yield is calculated...
The impurity [Fe<sup>3+</sup>–O<sup>2−</sup>] species in HZSM-5 zeolite is predominantly tetrahedrally coordinated and the photoactive centre for photocatalytic CO<sub>2</sub> conversion.
Nanodots are attractive stimuli-responsive luminescence materials for anti-counterfeiting and information encryption. However, their applications limited by low water solubility single-mode identification naked eyes under UV light illumination. Herein, we report one type of new nanodots, main-chain imidazolium-based ionic polymer dots (IPDs). There is no edge effect in IPDs, the groups homogenously distributed entire dot. IPDs exhibit high solubility, good stability, narrow size...

In this paper, we propose a visual saliency detection algorithm to explore the fusion of various models in manner bootstrap learning. First, an original bootstrapping model, which combines both weak and strong models, is constructed. image priors are exploited generate provides training samples for model. Then, classifier learned based on extracted from We use classify all salient non-salient superpixels input image. To further improve performance, multi-scale maps model integrated,...

Abstract Mutual transformations of various nitrogen compounds and their reaction mechanisms have been a subject great concern to the chemical, ecological environmental communities. In paper, reactions ion with small organic acids such as formic acid (HCOOH), acetic (CH 3 COOH) lactic (C H 6 O ) under ultraviolet illumination were investigated systematically. It was found that is easily reduced into NO x then further N 2 NH (in form in process. The carboxyl anion radicals hydrogen formed by...
Sex differences in the brain have long been a hot topic neuroscience. Previous studies on gender focused structures and functions related to higher-level cognition, but less attention has paid low-level sensory perceptual systems. Recently, growing number of shown that men women also show remarkable visual processing. In this paper, we started by reviewing behavioral neural evidences supporting notion sex system. We then proposed two potential explanations discussed evolutionary benefits...
