We employ an individual pool to increase the precision of the estimated convergence points of a population by using individual information from past generations. Better individuals from past generations are kept in the pool, and poorer individuals are replaced with new better individuals when the pool becomes full; convergence points for the population are thus estimated using those individuals from...
A 3D visible articulation system which utilizes audio-visual data to accurately simulate the 3D articulatory motion is developed in this paper. The 3D articulatory shapes are reconstructed from Magnetic Resonance Images (MRI). In order to synthesize accurate audio-visual results, articulatory parametric models are further developed and the Electromagnetic Articulography (EMA) data with synchronized...
Combining of nonlocal means and variational models can extend the ability of image processing such as texture image processing. In this paper, an implementation scheme of nonlocal variational models is proposed, which contains discretization, coordinate transformation, and dimension expansion. Firstly, continuous models are transferred to discrete model. Then we transform absolute coordinate to relative...
Visual question answering (VQA) is challenging because it requires a simultaneous understanding of both the visual content of images and the textual content of questions. The approaches used to represent the images and questions in a fine-grained manner and questions and to fuse these multimodal features play key roles in performance. Bilinear pooling based models have been shown to outperform traditional...
In this fast developing world, the number of motor vehicles is increasing rapidly but road resources remain limited, causing severe congestion problem of city traffic. In order to predict short-term traffic condition accurately, we propose a short-term traffic condition prediction method for urban road network based on improved support vector machine. As outliers inevitably exist in collected traffic...
In the implementation and verification of multi sensor fusion of vehicle positioning, we built a verification platform positioning algorithm combined simulation of Car Sim-Simulink to Car Sim, the vehicle model and the sensor output as the data source, and the noise, then in the simulink environment to build the fusion localization algorithm, and the real vehicle experiment using inertial laboratory...
For multiplierless FIR filter design and implementation, optimization of the product accumulation block (PAB) in transposed direct form structure has been ignored by most of the research. In this work, the power consumption of the PABs of FIR filters is studied theoretically and experimentally. It is shown that the PAB contributes most of the total power consumption in multiplierless FIR filters....
An open-slot antenna with wideband circular polarization has been designed and fabricated in this paper. The proposed antenna is composite of an open-slot, an asymmetric structure, and a patch-protruded feeding topology. The asymmetric structure can provide 90° phase difference in order to excite circular polarization for the satellite digital audio radio (SDAR) service system. By utilizing the patch-protruded...
A coplanar-waveguide (CPW)-fed monopole antenna for applications of the multi-system integration has been presented in this study. The enhancement of impedance bandwidth and circular polarization in the microstrip rectangular monopole antenna using following techniques: using asymmetrical CPW feeding structure and adding three grounded sleeve strips. By tuning the width of one side of the CPW ground...
A reconfigurable monopole with switchable frequency band and circular polarization has been demonstrated in this study. To achieve the switchable capability, two PIN diodes are placed into the fork-like conducted strip. When the bias voltages of the diodes are changed, the proposed monopole antenna possesses a right-hand circularly polarized (RHCP) wave at 1.57 GHz for the global positioning system...
In this paper, an improvement of fast image scaling algorithm, which produces image with wellpreserved edge, is proposed. The edge of the original image is detected by using four Sobel spatial operators. And the direction of edge is then measured by using two newly proposed edge detectors employing two threshold values. Based on these, pixels are interpolated adaptively, where edge pixels are interpolated...
Bilinear convolutional neural networks (BCNN) model, the state-of-the-art in fine-grained image recognition, fails in distinguishing the categories with subtle visual differences. We design a novel BCNN model guided by user click data (C-BCNN) to improve the performance via capturing both the visual and semantical content in images. Specially, to deal with the heavy noise in large-scale click data,...
In this paper, we use Poisson and drift-diffusion solver, effective Gaussian shape density of state model and Poole-Frenkel field dependent mobility model to simulate organic light emitting diode. Furthermore, to describe the model exactly, we also considered the mechanism of exciton diffusion and exciton annihilation. Finally, we study the influences of different doping region to the IV and exciton...
This paper proposes a 3D virtual animating head system, which can not only talk but also sing. With a reconstructed head mesh model, including external/internal articulators, from multi-source images, biology information are first used to visualize each phoneme with a musical note. The synchronicity between songs and articulatory movements is then modeled by a deep neural network trained on an audio/articulatory...
Wireless capsule endoscopy (WCE) can painlessly capture a large number of images inside the intestine. However, only a small portion of these WCE images contain hemorrhage. It is thus critical to develop automated hemorrhage detection method to facilitate the diagnosis of intestinal diseases. However, automated hemorrhage detection is complicated by 1) the extreme imbalance between the amount of hemorrhage...
The photonics toolkit includes waveguides, sources, detectors, modulators, etc., but lacks optical memory devices. Natural media with nonlinearities strong enough to show intrinsic bistability do not exist. Here, for the first time we experimentally demonstrate nonlinear nano-opto-mechanical metamaterials exhibiting optical bistability, leading to optical memory operation at sub-milliwatt power levels...
A new digital image multi-watermarking approach is proposed. Firstly watermark is synthesized by composing, conversion and scrambling of original multiple watermarks. Then watermark is embedded in middle frequency sub-bands of host image in wavelet domain, and the embedded intensity of watermark is determined adaptively by noise visibility function. Finally, extraction process adopts independent component...

Image denoisig is becoming an essential step for analysis of images which occurs due to the imperfections of sensors or during the transmission of data.
