虹膜

Oculocutaneous albinism type 4 (OCA4) is characterized by hypopigmentation of the skin and hair plus the characteristic ocular changes found in all other types of albinism, including nystagmus; reduced iris pigment with iris translucency; reduced retinal pigment with visualization of the choroidal blood vessels on ophthalmoscopic examination; foveal hypoplasia associated with reduction in visual acuity; and misrouting of the optic nerves at the chiasm associated with alternating strabismus, reduced stereoscopic vision, and an altered visual evoked potential.

疾病特征： 4型眼皮肤白化病（OCA4）的特点是皮肤和头发的色素减退以及所有白化病类型都有的典型的眼部改变，包括眼球震颤、虹膜色素减少而使其呈半透明状、视网膜色素减少而使得脉络膜血管在眼底镜检时可见、与中央凹发育不全导致的视敏度降低以及视神经交叉处路径错误引起的交替性斜视、立体感降低和视觉诱发电位改变。

When the iris is inflamed, it is likely that the ciliary body and choroid are involved too.

当虹膜是发炎，很可能睫状体和脉络膜都参与过。

This includes the iris, pupil, ciliary body and choroid.

这包括虹膜，瞳孔，睫状体和脉络膜。

One sector in the outer circularity of iris is used to represent the region of eyelash occlusions .

该算法基于canny算子检测图像中的眼睫毛；利用虹膜的外圆，提出了用一个扇形区域来表示眼睫毛遮挡区域。

Which let you diagnose and analyse the iris condition clear lyand quickly on the screen.

清晰的在萤幕上检测并分析虹膜的状况。

The histopathologic observations of corneas after penetrating keratoplasty in dogs: Thestructure of wholly transparent graft was the same as that of host cornea apart from the upperdonor-host junction where there was minimal irregularity of the corneal lamellae. However, thecorneal lamellae at the lower donor-host junction were neat. The graft with its central part beingtransparent only showed poor coaptation with recipient, in which the graft shifted inward and had marked wrinkles and folds in Descemet"s membrane. On the back of Descemet"s membranethere was hyperplastic stromal fibers that thickened the graft and partially adhered to iris.

5犬穿透性角膜移植术后角膜病理组织学观察完全透明的植片与植床结构一致，仅两者对合处上部纤维紊乱，而下方纤维排列整齐；中央透明的植片与植床对合不良，植片向植床方向嵌入，后弹力层皱缩、折叠，植片下方因有来自植床的基质纤维而增厚，部分对合处与虹膜粘连；浑浊的植片有比较完整的上皮层，植片约2／3深度的基质丧失原来纤维整齐排列结构，代以大量成纤维细胞增生。

Then feature extraction to the combined feature matrix is done by 2DFLD,and a fused feature matrix is constructed.

同时，利用2DFLD算法对组合特征矩阵进行融合，获得了人脸与虹膜的融合特征。

Secondly,the two original feature matrixes from face and iris image are integrated into one matrix,and a combined feature matrix is formed.

然后将人脸与虹膜的初始特征矩阵进行组合，获得组合特征矩阵。

First preliminary set within the edge of the iris, using the value of the image morphology, the largest connected domain and logical operators, such as processing algorithms.

首先初步定出虹膜的内边缘，利用二值化、图像形态学、最大连通域和逻辑运算等算法处理。

The iris analysts work cooly, disregarding the moving scene just enacted by those on the spot.

虹膜分析员冷静地工作着，摒除前场人员刚刚演出的感伤_他们要以科技审查一切情理。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
