摘要：合成混合金属/金属硫化物(Ag@CoS)与还原氧化石墨烯(rGO)的纳米复合材料(Ag@CoS/rGO),有可能用作超级电容器的电极。采用水热法成功地将Ag@CoS沉积在还原氧化石墨烯纳米片上,这意味着在还原氧化石墨烯骨架上生长出二维银和硫化钴基的六角形结构。对所合成的复合材料的结构、形貌和电化学行为进行研究。XRD结果表明,制备的纳米复合材料由于CoS和Ag的加入而呈六角结构。FTIR光谱中出现在470.33 cm^−1附近的谱带为Ag@CoS/rGO纳米复合材料中S—S键的吸收谱。采用扫描电镜(SEM)和透射电镜(TEM)分析材料清晰的六角结构,其晶粒尺寸从纳米级到微米级。该电极材料表现出良好的循环稳定性,当电流密度为0.5 A/g时,其比电容为1580 F/g。即使经过1000次循环,容量保持率也没有任何损失。由电化学行为研究结果可知,所制备的新型纳米复合材料非常适合用作电化学超级电容器的电极。

摘要：Study of image enhancement shows that the quality of image heavily relies on human visual system. In this paper, we apply this fact effectively to design a new image enhancement method for medical images that improves the detail regions. First, the eye region of interest （ROI） is segmented; then the Un-sharp Masking （USM） is used to enhance the detail regions. Experiments show that the proposed method can effectively improve the accuracy of medical image enhancement and has a significant effect.

摘要：This article presents a novel image interpolation based on rational fractal fimction. The rational function has a simple and explicit expression. At the same time, the fi＇actal interpolation surface can be defined by proper parameters. In this paper, we used the method of ＇covering blanket＇ combined with multi-scale analysis; the threshold is selected based on the multi-scale analysis. Selecting different parameters in the rational function model, the texture regions and smooth regions are interpolated by rational fractal interpolation and rational interpolation respectively. Experimental results on benchmark test images demonstrate that the proposed method achieves very competitive performance compared with the state-of-the-art interpolation algorithms, especially in image details and texture features.

摘要：In this paper, we present a tire defect detection algorithm based on sparse representation. The dictionary learned from reference images can efficiently represent the test image. As the representation coefficients of normal images have a specific distribution, the local feature can be estimate by comparing representation coefficient distribution. Meanwhile, a coding length is used to measure the global features of representation coefficients. The tire defect is located by both these local and global features. Experimental results demonstrate that the proposed method can accurately detect and locate the tire defects.

摘要：Parameterization is one of the key problems in the construction of a curve to interpolate a set of ordered points. We propose a new local parameterization method based on the curvature model in this paper. The new method determines the knots by mi- nimizing the maximum curvature of quadratic curve. When the knots by the new method are used to construct interpolation curve, the constructed curve have good precision. We also give some comparisons of the new method with existing methods, and our method can perform better in interpolation error, and the interpolated curve is more fairing.

摘要：In this paper we present a new image zooming algorithm based on surface fitting with edge constraint. In surface fitting,we consider not only the relationship of corresponding pixels between the original image and the enlarged image, but also the neighbor pixels in the enlarged image according to the local structure of original image. Furthermore, during surface fitting, more interpolation constraints are used in the new algorithm for improving the precision of the super sampling pixels. The experimental results show that the new method outperforms the previous methods which based on surface fitting.

摘要：According to X-ray image texture tire characteristics and abnormal distribution of the gray area, this paper studies a real-time defect detection method about the sidewall of tire. On the basis of the texture distribution characteristics of X-ray tire, we extract the cord information of the tire image by maximizing the distance of the categories after the gray value correction, then we use the morphology method and statistics method to process the image so that we can get the location and the size of impurities. We can classify the tires into different grades by the information. Compared with other methods, our method has the advantage that meets the needs of tire industry.

摘要：The problem of determining a minimum-area ellipse through three non-collinear points is discussed in this paper. We give the proof and construction of the minimum-area ellipse through three non-collinear points from the geometric point of view, and present a new method of determining knots. This method replaces the chord length, which is closer to the arc length of the mini- mum-area ellipse with arc length, and avoids the occurrence of ＇oscillation＇ and ＇loops＇. We compare the new method with the uni- form method, chord length method and the centripetal method. The comparison is performed on the quality of cubic spline curves using these methods. In most cases, the result of our method is better than others.
