And if you think about it, all these different societies have different geometric design themes they use. So Native Americans use a combination of circular symmetry and fourfold symmetry. You can see on the pottery and the baskets ... Here's an aerial photograph of one of the Anasazi ruins; you can see it's circular at the largest scale, but it's rectangular at the smaller scale, right?

In chapter 4, we compute the symmetry group, variational symmetry group, divergence symmetry group of some operator equation.

在第四章中計算了一些偏微分算子方程的對稱群，變分對稱群以及散度對稱群五月丁香花婷婷综合。

This can be done using computer vision technique and from symmetry property of potteries. The problem of recovering the 3D shape of a surface of revolution from images is addressed. The algorithm makes use of the symmetry properties of a surface of revolution and its silhouette to rectify the image such that the resulting silhouette exhibits bilateral symmetry.

在該方法的實現(xiàn)過程中男女人精品视频站在线观看，首先利用旋轉(zhuǎn)平臺獲取了旋轉(zhuǎn)體的影像，然后基于物方的空間圓重建方法精確測量旋轉(zhuǎn)體的上口亚洲精品一，從而得到旋轉(zhuǎn)體的旋轉(zhuǎn)軸亚洲色图五月天综合，再根據(jù)影像的方位元素對影像進行糾正，使得旋轉(zhuǎn)體的輪廓線在影像上的成像左右對稱网页升级自拍偷拍，最后直接用糾正后的影像精確計算旋轉(zhuǎn)體的形狀98在线视频。

First, the color-image was preprocessed with grayscaling, smoothing. The vertical gradient components of the image were found using the vertical mask of Sobel operator. Then the candidate areas with sufficient amount of edges were determined by calculating the gradient of edges. After finding possible vehicle candidates, the proposed method measured the prominent vertical symmetry of candidate areas and verified all possible candidates, as symmetry is an important feature of vehicle. The proposed method also figured out the vertical axis of symmetry and the width of the candidate vehicle.

算法首先對圖像進行灰度化、平滑去噪等預處理欧美激情动态图，使用Sobel算子垂直方向掩模計算圖像感興趣區(qū)域內(nèi)的邊緣梯度av男人的天堂综合网，確定候選區(qū)域；而后根據(jù)車輛圖像垂直邊緣具有對稱性的特點一级a片操逼逼免费观看视频，分析候選區(qū)域的對稱性強弱久久精品视频还得看这里，并計算其對稱軸位置和車輛寬度。

Based on a comprehensive study of drilling and log data, sequences of short-term base-level cycle of turbidite fan in Yanchang Formation of Triassic in Longdong area are divided into three basic structure types: up - deepening non - symmetry, up -shallowing non ?symmetry and symmetry ones according to recognition sign of the interface of the short - term base - level cycle.

Multiple packed cylinders and more complex structures such as helices or stacked toroids spontaneously form for low-symmetry and high-symmetry cross sections, respectively. Furthermore, the symmetry and domain spacing of these structures can be altered by the shape and size of the confining pore.

我們發(fā)現(xiàn)當孔的對稱性很低時操逼公司，共聚物主要形成柱狀結(jié)構(gòu)；而當孔的對稱性較高時无码精品视频在线观看网址，共聚物形成了多螺旋91网国产、層疊圓環(huán)等新奇結(jié)構(gòu)。

Their ability to draw the picture accurately is impaired especially when the symmetrical axis is tilted. Parallelograms are easily mistaken for line-symmetry diagrams. Point-symmetry diagrams tend to prevent correct identification of line-symmetry diagrams.

學童在畫線對稱圖形另一半的能力有待加強欧美性交播播，尤其當對稱軸是歪斜時會影響學童畫圖的準確性爆乳美女裸体性插视频网站；平行四邊形易被當成線對稱圖形日韩性交网址，點對稱圖形也會干擾線對稱圖形的判定。
