三幅一组

Two pairs of vanishing points of orthogonal directions from each image are obtained by using the concept of cross ratio and harmonic conjugate in projective geometry and the orthogonal property of the two diagonals on a square. All intrinsic parameters are calculated linearly after capturing the template from at least three shooting angles. Errors of edge detection and line fitting are avoided because the method does not require image matching.

充分利用了射影几何中交比和调和共轭的知识以及正方形模板对角线相互垂直的性质，根据一幅模板图像可以得到两组相互正交的消失点连线，在至少三个不同方向拍摄的图像上线性求解出摄像机的所有内部参数。

All horizontal, all 18 inches high and 24 inches wide, they include a few single-panel works and one triptych; most are diptychs.

都是横幅，18英寸高成24英寸宽，处一些单幅作品和一个三幅一组之外，大多是双幅一组的。

Nowhere is it more engaged than in the triptych, where panels show views of a rock band playing on a club's stage, fronted by a young female singer.

没有比那个三幅一组的描绘一个以一年轻女歌手为主的摇滚乐队在一个Club台上表演的作品更吸引人的。

Whether a performer being checked out by an unexpected fan, a symbol of youthful rebellion under the watchful eye of a representative of government control or perhaps art being metaphorically monitored by shadowy proscriptions, the triptych mesmerizes.

不论是一个演员被一个不可预料的歌迷关注，还是在政府代表严格监控下年轻人的逆反的象征或是艺术被阴暗的禁止所监控的比喻，这三幅一组的作品深深触动人心。

There, he said, the auctioneer talked up two "museum-quality" Picasso prints appraised at more than $35,000 each and a trilogy of Salvador Dali prints valued at $35,000 as a set.

他说，拍卖商吹捧两幅「博物馆品质」的毕卡索版画，每幅估价都超过3万5千美元。另外还有达利估计价值3万5千美元的三幅一组版画。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
