目的:评价模糊与噪声对不同图像识别算法在人耳图像识别过程中的影响。方法:对500个清晰图像进行模糊和热噪声处理,比较方向梯度直方图(HOG)、局部相位量化(LPQ)和局部二值模式(LBP)三种不同的特征提取算法对生物识别性能的影响。结果:HOG、LPQ和LBP算法对清晰人耳图像的识别率都很高,在无噪声和模糊等信号衰减的情况下,识别率分别达到了85.96%、95.62%和91.36%。在这三种算法中
为了探究二萜类化合物蓝萼甲素(glaucocalyxin A)对拟南芥4种磷脂酶的影响,以蓝萼甲素为供体,以哥伦比亚野生型拟南芥(Col-0)和4个拟南芥磷脂酶突变体株系(pla1-1、pla2-1、plc1-1和pldδ-2)为受体植物,通过施加不同浓度的蓝萼甲素(0、20、100μmol·L-1)对5个拟南芥株系组织膜透性和渗透调节物质进行研究。结果表明:外施不同浓度的蓝萼甲素后,拟南芥5个株
采用室内培养方法,通过不同剂量和配比试验,研究脲酶抑制剂N-丁基硫代磷酰三胺(NBPT)、硝化抑制剂2-氯-6-(三氯甲基)吡啶(CP)及其两者组合对黄泥田土壤氨(NH3)挥发速率、累积特征及动力学特性的影响。结果表明:尿素施用于黄泥田土壤后3天NH3挥发速率逐渐到达峰值,随后下降趋于平稳;与单施尿素处理相比,不同剂量CP处理会加剧土壤中NH3挥发,增加NH3挥发速率峰值10.9%;不同剂量NBP
We study the feasibility and safety of human lung hyperpolarized(HP)~(129)Xe magnetic resonance imaging(MRI).There is no significant change in physiological parameters before and after the examination
La~(3+) and Ce~(3+) have positive effects on plant growth and production. Although it is well known that rare earth elements promote cell growth. the biological effects of La~(3+) and Ce~(3+) on callu
今年3月23日是第五十八个世界气象日,主题是"智慧气象",旨在凸显发展智慧气象在防御和减轻极端天气、气候和水事件影响,保护人类生命财产安全中的关键作用。世界气象日期间,中国气象局和各地气象部门围绕主题,结合气象防灾减灾、生态文明建设、应对气候变化等社会热点,开展了"智慧气象"互动体验、科普观测展、气象台观测
基于宗教地理学相关理论,以青海省清真寺为研究对象,运用空间分析方法对青海省伊斯兰教清真寺文化传播的时空演变特征进行研究.结果表明:(1)青海省清真寺的数量随时间的增长呈波动上升趋势,按增长曲线特征可分为4个阶段:元明时期的缓慢增长阶段、清代的波动增长阶段、民国时期的平稳增长阶段和新中国成立以来的跌宕发展阶段;(2)随历史的演进,清真寺重心迁移幅度不大,其重心移动距离呈不断减小的趋势,移动方向呈东南
Small earthquake data from the Pishan MS6.5 aftershocks is collected by the Xinjiang Regional Digital Seismic Observation Network.Five parameters of the focal region are obtained by micro genetic inve
After the 2015 M_S8. 1 Nepal earthquake,a strong and moderate seismicity belt has formed in Tibet gradually spreading along the northeast direction. In this paper,we attempt to summarize the features
Research on the differential uplifting in the Palongzangbu region is crucial to understanding the tectonic deformation mechanism and establishing the model of the faulted blocks in the region of the e
