在眼睛最外层起保护作用的薄膜是角膜。光线通过这层薄膜后,就进入了虹膜。
The protective bit at the front of the eye is the cornea and once light passes through this membrane, it passes through the iris.
在数据库中有记录的孩子走失被找回后,扫描虹膜便可迅速确定其身份,比DNA身份核验更加快捷。
If a child who is registered on the database goes missing and is found, an iris scan will be able to quickly determine his or her identity, much faster than DNA identification.
最后对定位后的虹膜图像进行了归一化。
采用二值化的方法获得瞳孔的粗定位的参数后,由于瞳孔和虹膜的外边缘近视为同心圆,该参数可用作提取虹膜外边缘的基础。
After finding parameter of coarse location, the inner and outer circle can be got based on the parameter because the circle of pupil and circle of iris nearly have the same center.
结果:长期用缩瞳剂造成虹膜后粘连的发生率为46 .7% ;
Results:The rate of posterior synechia because of long term use of miotic is 46.7%.
目的评价虹膜夹型人工晶状体虹膜后植入治疗无后囊膜或后囊膜不足以支撑的无晶状体眼临床疗效。
Objective To evaluate the therapeutic efficacy of posterior iris fixation of iris-claw intraocular lens (IOL) implantation on aphakia eyes with non-posterior-capsule or less capsule supporting IOL.
最后得到光斑填充后的虹膜图像,消除了虹膜图像中灰度值突然变高的噪声点。
Noises that gray values increase sharply will be removed and iris images without bright holes will be left.
结果78 9%的患者术后矫正视力达0 5以上,术后并发症包括晶状体后囊浑浊与虹膜后粘连。
Results the corrected visual in 78.9% of the patients reach to 0.5 or better. Postoperative complications included posterior capsule opacification and iris posterior synechiae.
结论:与PK手术植片衰竭相关的高危因素包括角膜血管化、再次移植、无晶状体眼、人工晶状体眼、虹膜前或虹膜后黏连;
Conclusion:The risk factors for graft failure after PK were corneal vascularization, regraft, aphakia or pseudophakia, presence of anterior or posterior synechia.
目的探讨眼外伤后无虹膜无晶状体眼的治疗方法。
Objective To investigate the effect of black diaphragm intraocular lens implantation in the management of aphakia with traumatic aniridia.
结果最常见的并发症是角膜水肿 (2 3% )、虹膜损伤 (16 % )、后囊破裂 (15 % )。
Results The main complications were corneal edema (23%), iris injury (16%) and posterior capsule rupture (15%).
预处理过程中对虹膜的精确定位,使定位后的虹膜图像具有平移、尺度和旋转的不变性。
Precision locating for iris in the process of preprocessing makes iris image have invariance in translation, size and rotation.
最常见的关节外表现是眼损害,可出现结膜炎、虹膜炎或前葡萄膜炎,最多见的是后两种。
The most common extra-articular manifestations is eye damage, there may be conjunctivitis, or inflammation iris anterior uveitis, the most common is that the latter two.
融合时利用MPM(最小最大概率机)融合策略对两虹膜的得分值进行融合,最后利用融合后得分值决策。
When fusing, a novel fusion strategy using minimax probability machine (MPM) is applied to generate a fused score for the final decision.
