Using the way combining the mathematic morphology top - hat and gauss matched filtering can effectively reduce the influence of the inherent fovea and the marginal noise brought forth by the retinal camera caliber in retinal image and increase the precision of retinal image segmentation and feature point extraction 文中提出了采用灰度數學形態學中的top - hat變換和高斯匹配濾波相結合的方法,用來有效的降低視網膜熒光圖像中固有的小窩現象及眼底照相機的口徑所引起的視網膜圖像邊界像素噪聲,極大的提高了圖像分割及特征提取的精度。

Moveover , conventional mosaic structure and new fovea x3 structure image sensors and comparison of the cmos and ccd image sensors are also introduced 其中對傳統的馬賽克結構圖象傳感器和新出現的foveax3結構的圖象傳感器結構, cmos傳感器和ccd傳感器的比較都進行了詳細的介紹。

The risk factors include age of over 56 years , size of rped over 1 dd and involvement of fovea 新生血管發生之危險因子包括年齡大小,剝離病灶?圍大小,及中心窩之有無侵及。

The fovea is the area of maximum visual resolution(but not maximum sensitivity) . 黃斑是具有最大視覺清晰度(但不是最大靈敏度)的區域。

The fovea has only cones, and the blind spot or papilla has no receptors . 中央凹的部分只有錐細胞,而盲點或神經乳頭部分無視細胞。
