针对国内交通标志的属性特征,提出了一种基于颜色和形状的交通标志分类算法。采用RGB模型分量值互减的方法对自然背景下的交通标志图像进行分割,提取出感兴趣区域,对标志区域进行形态学处理、边缘检测,提取标志外层轮廓。利用Hough变换识别交通标志线性特征。在识别交通标志颜色和几何形状的基础上,利用交通标志的分类知识实现交通标志的快速分类。实验结果表明,该方法容易实现,满足实时性要求,并能达到较好的分类效果。

瘦素(Leptin)通过作用于长型受体(OB-Rb)调控乳腺的发育和泌乳。为阐明小鼠乳腺发育循环过程中瘦素和OB-Rb的表达含量和表达部位的变化,采用间接免疫荧光和激光共聚焦显微技术对青春期、妊娠期、泌乳期和退化期的小鼠乳腺中瘦素和OB-Rb的表达含量和表达部位进行检测。结果表明:乳腺脂肪垫、导管上皮细胞和腺泡上皮细胞中均可检测到瘦素的表达,导管上皮细胞和腺泡上皮细胞的基底侧可以检测到OB-Rb的表达。乳腺中瘦素和OB-Rb的表达变化趋势一致,在青春期最高,妊娠期下降,泌乳期维持低水平,退化期重新上调,恢

采用密度泛函理论框架下的第一性原理平面波计算方法,系统研究了不同应力作用下GaN 的电子结构和光学性质,对比分析了外压调制对GaN 的能带结构、态密度和光学性质变化的影响。计算结果表明:随着外应力的逐渐增加,Ga—N 的键长逐渐变小,布局数逐渐增加,共价性明显增强,离子性减弱。电子结构计算结果显示导带向高能方向漂移,而整个价带向低能方向漂移,禁带带宽明显被展宽,Ga 原子的3d 态电子与N 原子的2p 态电子的杂化程度增强。光学性质计算结果揭示了在没有应力的作用下,在1.6 eV 附近开始出现吸收边。随着
Wide-range optical sensors based on a single ring resonator are investigated theoretically and experimentally. The sensor worked at the TE and TM modes simultaneously. Because the sensitivities of the TE mode and TM mode are different, the TE mode is used
