Scale–orientation joint restriction criteria are proposed achieve robust matching for Moreover, descriptor each keypoint also refined overcome gradient and...
Superpixel segmentation partitions an image into perceptually coherent segments of similar size, namely, superpixels. It is becoming a fundamental preprocessing step for various computer vision tasks because superpixels significantly reduce the number inputs and provide meaningful representation feature extraction. We present pixel-related Gaussian mixture model (GMM) to segment images GMM weighted sum functions, each one corresponding superpixel, describe density pixel represented by random...
Region growing method is a classical in medical image segmentation. To overcome the difficulty of manual threshold selection and sensitivity to noise, an adaptive region based on gradients variances along inside boundary curve proposed. Firstly, we use anisotropic diffusion filter preserve edge information. Then new model given, which chooses mean variance reciprocal gradient as research subjects. The objective function add two elements about mentioned above. minimum sum optimum result...
Flexible ferroelectrics being exploited as energy harvesting and conversion materials are highly desirable for wearable skin-mountable electronic devices. As one of the most typical ferroelectric polymers, poly(vinylidene fluoride) (PVDF) has been widely used in modern systems devices, whose performance relies heavily on its β phase content. In this work, to achieve high-β-phase-content PVDF, we first introduced CoFe2O4 nanoparticles into PVDF. With incorporation an effective polymer...
In this contribution, we demonstrate the optimization of microstructures Pb0.85La0.1(Zr0.65Ti0.35)O3 (PLZT) relaxor ferroelectric ceramics and subsequent enhancements in their polarization electrical resistivity by using a hot-pressing process. The resulting superior breakdown strength hot-pressed PLZT enables application high electric field to induce giant electrocaloric effect, which adiabatic change temperature (ΔT) isothermal entropy (ΔS) are around 2 times greater than those samples...
Superhydrophobic polytetrafluoroethylene (PTFE) surfaces with accurately and continuously tunable water adhesion were fabricated by a simple rapid method of picosecond (ps) laser direct ablation. By simply changing scan intervals (LSIs) from 5 to 140 μm, three laser-ablated PTFE surfaces, i.e., the two superhydrophobic ultralow adhesion, ordinary hydrophobic surface ultrahigh could be obtained. Here, sliding angles droplets on these varied about 1° 90°. XPS analysis suggested that continuous...
Abstract The membranes with special surface wettability have attracted considerable attention, especially in the practical applications of oil-water separation. Here, we presented a simple and rapid method picosecond (ps) laser direct ablation then drilling to fabricate high-performance separation polytetrafluoroethylene (PTFE) membrane. It was found that as-prepared rough PTFE had ca. 0° contact angle (CA) oil air above 150° CAs water or oil, respectively, exhibiting superoleophilicity...
Image entropy and empirical mode decomposition (EMD) are effective methods for target detection.EMD algorithm is a powerful tool adaptive multiscale analysis of nonstationary signals.A new technique based on EMD modified local proposed in small detection under sea-sky background.With the algorithm, it valid to estimate background get image by removing from original segmenting method.The data experiments show validity algorithm.
Dispersed uniform submicron-sized silver spheres were prepared by selective laser heating in the silver-containing precursor solution, which was produced dissolving irregular Ag2O aliphatic amine. By optimizing process conditions, range of 578 ± 109 nm obtained. The smooth surface morphology and solid structure studied SEM TEM. content characterized XRD EDS. Finally, mechanism formation also discussed detail.

Geometric methods are very intuitive and provide a theoretical foundation to many optimization problems in the fields of pattern recognition machine learning. In this brief, notion scaled convex hull (SCH) is defined set results exploited support it. These allow existing nearest point algorithms be directly applied solve both separable nonseparable classification successfully efficiently. Then, popular S-K algorithm has been presented context SCH framework. The analysis some experiments show...

Removing the geometric distortion and space-time-varying blur caused by atmospheric turbulence from a given image sequence remains challenge. Since are two different kinds of distortions interact with each other in process restoration, it is difficult to extract features that useful restoration when images experience multiple distortions. In this article, we propose new scheme based on representation. The invariants maximum gradient used represent sharpness an frame, respectively. proposed...
