小波域中CSF频率与方向加权的图像质量评价方法

电子学报 , 2014, DOI: 10.3969/j.issn.0372-2112.2014.07.005
Abstract: 为解决结构相似度算法的图像质量评价缺陷,提出一种在小波域中,根据CSF的频率与方向加权的图像质量评价方法.该方法将图像的小波域多分辨率特性与CSF的带通特性有机的相结合,得到一种基于结构相似度的评价新方法.算法首先将频率归一化的CSF曲线按照1倍频程分解成5份,然后进行5级CDF9/7双正交小波分解与重构,得到一个低频子带LL和多个中高频子带HHi、HLi及LHi,根据不同的频率,不同的方向分配不同的权重,分别与相应的子频带SSIM值相乘,然后累加运算,得到小波域的加权图像结构相似度WWSSIM.实验表明,WWSSIM方法的单调性、一致性、准确性评价指标较高,更接近人类主观视觉感受.

Abstract: 由于探测器灵敏度的限制,激光雷达、夜视等图像各点的相对灰度较低。基于更快速的混合蛙跳算法(AFastShuffledFrogLeapingAlgorithm,FSFLA)提出了一种图像自适应快速增强算法。该算法采用了一种具有更大搜索范围、更快的收敛速度的快速混合蛙跳算法,降低了运算时间。它应用于微光图像的处理方面上,较传统的SFLA算法能更快地达到图像增强的效果,更适用于实际应用场合。在给出24个初值的情况下,传统的SFLA算法须迭代平均20次才能达到稳定的效果,而FSFLA仅需6次,因而大幅度地提高了运算时间。

Abstract: ?采用大孔树脂对原花青素粗品进行分离纯化。比较了ab-8、dm130、ads-17三种大孔树脂对原花青素的吸附和解吸能力,选择ab-8型大孔树脂为吸附树脂。对ab-8大孔树脂吸附解吸条件进行优化,探讨上样流速、解吸流速和解吸剂体积分数3个因素对分离纯化效果的影响。结果表明:ab-8大孔树脂提纯工艺的最佳条件为上样流速2ml/min、解吸流速1ml/min、解吸剂体积分数50%。通过花青素反应与高效液相色谱-质谱对提取物进行定性分析,证实该提取物中含有的原花青素为儿茶素、表儿茶素和二聚体,且原花青素纯度为96.65%。

Abstract: 目的:了解南宁地区育龄人群泌尿生殖道支原体感染状况及其耐药性特点。方法:对2013年4月~2015年3月在本院就诊的2435例患者生殖道分泌物采用支原体培养鉴别计数药敏试剂盒进行解脲脲原体(Uu)和人型支原体(Mh)检测。结果:支原体感染率为44.97%,女性感染率为60.01%高于男性的29.33%,其中Uu、Mh和Uu+Mh感染率分别为33.96%、1.85%和9.16%。3种感染模式均敏感的有交沙霉素、多西环素和美满霉素,均耐药的为环丙沙星;Uu+Mh对12种抗菌药物耐药率高于Uu,Mh对除交沙霉素外的大环内酯类耐药率高于Uu+Mh,而对除左氧氟沙星外的喹诺酮类、四环素类耐药率低于Uu+Mh。喹诺酮类、大环内酯类和四环素类耐药率分别为84.11%、50.95%和29.95%。结论:南宁地区泌尿生殖道支原体感染率较高,女性高于男性,以Uu感染为主;支原体对常用抗生素的耐药性严重。
Objective: To investigate the prevalence of Mycoplasma infections and their drug resistance in the urogenital tract among reproductive population. Methods: Mycoplasma Urealytium and Mycop-lasma hominis were cultured in the urogenital tract specimens form 2435 patients from April 2013 to May 2015, and their drug sensitivity were analyzed. Results: The rate of Mycoplasma infection was 44.97%. It is higher in female (60.01%) than in man (29.33%), and they were 33.96%, 1.85% and 9.16% in patient with Uu, Mh and Uu+Mh infection. Mycoplasma was sensitive to josamycin, doxycycline and minocycline, and resistant against ciprofloxacin. The drug resistance of Uu+Mh for 12 kinds of antibiotic is much higher than Uu. Mh is more resistant to Uu for macrolide antibiotics except for josamycin, and it is low for quinolones and tetracyclines, except for levofloxacin. The rate of drug resistance for quinolones, macrolide antibiotics and tetracyclines was 84.11%, 50.95% and 29.95% respectively. Conclusion: The infection rate of Mycoplasmain the urogenital tract is high in Nanning. It is more obvious in female, mainly the infection rate of Uu. The drug resistance of mycoplasma for antibiotics was extensive.

Abstract: Functional MRI was used to explore the role of language experience in shaping the neural substrates of phonological processing. Twelve Chinese children who had very limited exposure to second language (L2), i.e., English, were scanned while they were performing visually presented rhyme judgment tasks in their two languages. We found that the phonological processing of subjects' native language and their newly obtained L2 elicited overlapping activation in the left inferior frontal region. More important, thought the L2 tasks were more difficult and thus caused more intensive activation in bilateral parietal lobule, the Broca's area was less intensively activated in the L2 tasks. These results confirm and extend the view that the involvement of Broca's area in phonological processing is gradually increased as a function of language experience.

Abstract: 提出了一种基于复Wishart分布随机距离的PolSAR图像边缘检测方法,将统计学中的随机距离理论引入PolSAR图像边缘检测中,依据的主要原理是边缘两侧类别之间随机距离的大小与边缘的方向和两侧类别差异的高度相关性。通过模拟数据对随机距离检测边缘的性能进行了全面分析,表明随机距离具有准确的边缘定向和定位能力。并利用基于复Wishart分布随机数生成器模拟的PolSAR图像和一景机载全极化SAR图像进行了验证。试验结果证实了该方法检测边缘的效果。
