In the facial expression recognition task, a good-performing convolutional neural network (CNN) model trained on one dataset (source dataset) usually performs poorly another (target dataset). This is because feature distribution of same emotion varies in different datasets. To improve cross-dataset accuracy CNN model, we introduce an unsupervised domain adaptation method, which especially suitable for unlabelled small target dataset. order to solve problem lack samples from dataset, train...
Three-dimensional (3D) shape measurement based on fringe pattern projection techniques has been commonly used in various fields. One of the remaining challenges is that camera sensor saturation may occur if there a large range reflectivity variation across surface causes errors. To overcome this problem, novel method proposed to avoid image and maintain high-intensity modulation for measuring shiny surfaces by adaptively adjusting pixel-to-pixel intensity according reflectivity. First, three...
Abstract Background Long non-coding RNAs (lncRNAs) play a vital role in the genesis and development of human cancer. LncRNA MIR99AHG has been reported to be upregulated acute myeloid leukemia (AML); however, its function gastric cancer (GC) is still not clear. Here we were aiming screen prognostic lncRNA candidates explore GC. Methods We have preliminarily screened some candidate biomarkers GC tissues through analyzing microarray datasets. The expression level cell lines was monitored via...
Abstract The accurate determination of the position and orientation moving objects from images is a critical challenge in visual sensing, with significant implications for robotics, augmented reality computer vision. Traditional pose estimation methods often fail complex scenarios due to inconsistent imprecise feature extraction. This research introduces novel quadric fitting optimization framework that exploits compact representation ellipsoids robust motion analysis. We propose Manhattan...
Abstract Artificial intelligence (AI) based drug design has demonstrated great potential to fundamentally change the pharmaceutical industries. Currently, a key issue in AI-based is efficient transferable molecular descriptors or fingerprints. Here, we present hypergraph-based topological representation, (weighted) persistent cohomology (HPC/HWPC) and HPC/HWPC-based fingerprints for machine learning models design. Molecular structures their atomic interactions are highly complicated pose...
In order to study the stability control mechanism of deep soft rock roadway and active support technology anchor-grouting flexible bolt, this paper takes west wing transportation Yuandian No. 2 Coal Mine Huaibei Mining Co., Ltd., Huaibei, China as research background. By analyzing occurrence conditions failure characteristics surrounding structural mechanical properties combined with elastic–plastic superimposed arch theory analysis, superposition community theoretical model joint scheme...
Specular and strong reflections are the main problems encountered during part image defect inspection of shiny or highly reflective surfaces.In this letter, we propose an improved illumination method for inspection.A diffuse light source is designed based on physics analysis reflection.The distribution intensity simulated according to a known model verify uniformity source.Experiments show that expressivity when using proposed has better performance.The optical not only suitable detection...
An ultrasonic transducer is a key component to achieve imaging. This paper designs new type of Microelectromechanical Systems (MEMS) based capacitive and linear array on the transducer. Through directivity analysis, it can be found that its weak due small size designed transducer, but very strong. In order further suppress sidelobe interference improve resolution imaging system quality, Dolph-Chebyshev weighting method Taylor are used process −40dB suppression, satisfactory results obtained,...
This paper presents an approach for estimating and then removing image radial distortion. It works on a single does not require special calibration. The is extremely useful in many applications, particularly those where human-made environments contain abundant lines. A division model applied, which straight line the distorted treated as circular arc. Levenberg–Marquardt (LM) iterative nonlinear least squares method adopted to calculate arc’s parameters. Then “Taubin fit” applied obtain...
Roof overhang is one of the most easily damaged parts low-rise buildings during windstorms. To investigate wind-induced pressure distributions and forces on roof a typical building, field monitoring two typhoons detailed wind tunnel test are conducted in this paper. Correlation analysis performed to analyze pressures upper lower surfaces overhang. Moreover, cross-comparisons among testing results, full-scale measurements, design provisions made for validation purposes. The comparative study...
Imagery registration is a fundamental step, which greatly affects later processes in image mosaic, multi-spectral fusion, digital surface modelling, etc., where the final solution needs blending of pixel information from more than one images. It highly desired to find way identify regions among input stereo pairs with high accuracy, particularly remote sensing applications ground control points (GCPs) are not always available, such as selecting landing zone on an outer space planet. In this...
Abstract Existing studies about wind pressure on agricultural greenhouse buildings concentrate the mean while ignoring systematic research fluctuating characteristics and influence of roof shape characteristics, which are closely associated with wind-induced damage mechanism. In this study, two typical tropical islands selected as prototypes to conduct measurement experiments in tunnel. Based time series for greenhouses, distribution pattern localized high-pressure generation mechanism...
The synthesis and characterization of two new soluble poly(p-phenylenevinylenes) (PPVs) are reported. polymers poly(2-(2',5'-bis(octyloxy)benzene)-1,4-phenylenevinylene) (BOP-PPV) poly(2-(2',5'-bis(octyloxy)benzene)-5-methoxy-1,4-phenylenevinylene) (BOPM-PPV). Both have been polymerized at high low temperatures to study the formation structural defects. It is shown that both methoxy groups as side chains polymerization decrease content defects in final polymer. As a consequence, with lower...
