At first, the optimization formulas of the structuring element are derived in the case of erosion and dilation. Then, adaptation formulas for an arbitrary composition of erosions and dilations are obtained. 通过将腐蚀与膨胀运算用隐函数表示,推导出腐蚀与膨胀运算中结构元的优化公式,由此进一步可得到任意组合形态滤波器的自适应优化公式。
Joint ρ-dilations and Generalized Joint Numerical Ranges 联合ρ-膨胀与广义联合数值域
The dilation of the aortic sinus was detected in 16 children(( 67%),) and the dilations of left ventricle and mitral regurgitation were found in 3 children ( 13%) with echocardiogram. 超声心动图主动脉窦增宽16例(67%),左心室增大及二尖瓣返流3例(13%)。
The relationship between the number of ovipositions and ovariole dilations of Anopheles sinensis and an. ANTHROPOPHAGUS 中华按蚊和嗜人按蚊产卵次数与卵泡管膨大部数的关系
Case is multiple localized cysts of intrahepatic bile ducts. CT finding is multiple limitative dilations of intrahepatic bile ducts. 2 cases are cysts in both intrahepatic and extrahepatic bile ducts. 结果:10例胆总管呈圆形或椭圆形扩张,1例肝内胆管呈多发性局限性囊状扩张,2例同时累及肝内、外胆管,2例胆系造影CT扫描,造影剂进入囊肿内。
This paper describes a new scheme for the analog implementation of Gaussian wavelet transform using Pade approximation and log-domain filter circuits. The circuits are composed of analog filter banks whose impulse responses are the first derivative of Gaussian and its dilations. 提出了基于Pade逼近与对数技术的高斯小波变换的滤波器电路实现方法,其实现电路由冲激响应为高斯一阶导数的滤波器组构成。
Conclusions: IPCV always masqueraded as AMD, but they were best identified with ICGA that could clearly show the branching choroidal vascular networks with polypoidal dilations. 结论:IPCV易误诊为湿性型AMD,但其ICGA显示的分支状脉络膜血管网及末梢的水螅状血管扩张有助于两者的诊断与鉴别诊断。
