Based on study of relationship between the average quadric error and the surface curvature, a variable resolution surface reconstruction algorithm was proposed.

在研究平均二次誤差與曲面曲率關(guān)系的基礎(chǔ)上三级大黄，提出了變分辨率的曲面重建算法。

And the matching point pairs are obtained by comparing the Euclidean distance of the Zernike moments,which are computed around a circular neighborhood centered at the feature point.Then the transform parameters are computed through the correct mapping model.Finally,the weighed average method is used to achieve image mosaic.

該算法利用曲率尺度空間角點檢測法提取特征點a片成年人黄色网站免费，通過比較各特征點圓形鄰域Zernike矩的歐式距離得到匹配點對亚洲图库在线，然后利用正確的映射模型計算出變換參數(shù)，最后采用加權(quán)平均法得到圖像的拼接結(jié)果国产丝袜久久久久一区二区三区。

The hybrid gel film on curved surface can replace traditional light-sensitive lacquer, and improve the grating's stability. The VLSG with the line density of 80l/mm was fabricated on a concave lens surface with curved radius of 100mm.

采用這種方法在曲率半徑為100mm的凹球面基底上制作了平均線密度為80l/mm的光柵蝌蚪黄片小辣椒视频，并用環(huán)境掃描電鏡以及數(shù)字圖像處理法檢測了光柵的線密度分布。

The average central cornea curvature is in direct proportion to the average diameter of the flap and the pedicel.

平均中央角膜曲率越高，角膜瓣的平均直徑越大久久国产无码专区一区二区，角膜瓣蒂長度越長在线免费看黄高清无码网站。

Keratometry measurements were obtained preoperatively, at postoperative 1 week, 1 month and 6 months respectively. SIAs were analyzed by "Cravy vector method". The mean SIA and uncorrected visual acuity were compared among the groups up to 6 months postoperatively.
