FMI成像测井失真图像的修复及其地质应用

针对FMI成像测井常见的图像失真问题,根据地层沉积过程中空间小范围内岩石结构和纹理具有渐变性和相似性的原理,利用数字图形图像处理领域常用的图像修复技术进行失真图像的复原,并针对FMI图像的特殊性质进行了方法的改进.实际效果证明,该方法可以非常逼真自然地修复受损图像,并将其应用到恢复裂缝形态、准确计算裂缝参数以及消除钻具刮擦及极板污染造成的图像中非地层因素影响,从而为测井和地质分析提供地层真实的FMI图像.     

Speakers gaze at objects while preparing intentionally inaccurate labels for them.

When describing scenes, speakers gaze at objects while preparing their names (Z. M. Griffin & K. Bock, 2000). In this study, the authors investigated whether gazes to referents occurred in the absence of a correspondence between visual features and word meaning. Speakers gazed significantly longer at objects before intentionally labeling them inaccurately with the names of similar things (e.g., calling a horse a dog) than when labeling them accurately. This held for grammatical subjects and objects as well as agents and patients. Moreover, the time spent gazing at a referent before labeling it with a novel word or accurate name was similar and decreased as speakers gained experience using the novel word. These results suggest that visual attention in speaking may be directed toward referents in the absence of any association between their visual forms and the words used to talk about them.

本文基于实验型偏振CCD相机,在自然光照条件下,进行了自然目标和人工目标的偏振图像数据获取实验、结果显示:偏振图像信息与强度图像相比,低照度（阴影等）部分,特别是边缘信息得到了增强。从模拟目标样品的实验结果看,偏振信息对纹理探测效果十分明显,结合边缘信息的增强作用,偏振探测在军事侦察及伪装检测等方面有着广阔的应用前景。     

基于整型小波变换的遥感图像压缩

对给定的遥感图像采用基于“提升”（Lifing)算法的整型小波变换，然后对变换后的小波域图像进行编码。在小波域编码时，采用逐次近似量化和LZ77方法编码。当量化门限较高时，则有用EZW方法直接对小波域上的图像进行编码，当门限较低时，则对EZW编码后的残差信息进行LZ77编码，文章用上述方法实现了遥感图像的无损压缩，提高了图像的压缩效果。

Measurements of turbulent mass transport of a circular wall jet

The results of a laboratory investigation on the turbulence characteristics of a circular three-dimensional turbulent wall jet are presented. Measurements were taken up to 50 nozzle diameters using combined particle image velocimetry and planar laser induced fluorescence. The results showed that the induced turbulence was still evolving in the present range and had not achieved similarity. While the turbulent intensity for both velocity and concentration increased downstream, the turbulent mass transport showed a decline over distance for both the streamwise and spanwise directions, implying weakening dispersion from the jet core.
