基于AutoCAD和3DSMAX的虚拟校园三维场景构建研究

当前的虚拟校园三维场景构建方法是利用osgEarth获取GoogleEarth数据,构建虚拟校园三维地图,然后依据本地地形信息与三维场景模型完成对虚拟校园的三维场景构建。该方法在三维场景构建过程中没有考虑到校园后续建设发展,只凭现在所需进行三维场景构建,导致虚拟校园三维场景杂乱,存在虚拟校园三维场景构建顾虑不周的问题。为此,提出一种基于AutoCAD和3DSMAX的虚拟校园三维场景构建方法。该方法首先利用Kinect的RGB深度摄像头获取校园平面数据、影像数据和贴图资料,采用相机阵列合成算法对所得校园图像进行特征提取,然后依据非局部均值滤波方法对获取的校园图像进行去噪操作,最后利用边缘方向和梯度表示中的结构方向与强度,对校园图像外轮廓的纹理特征进行收敛,依据外轮廓纹理特征收敛实现校园图像内轮廓的准确定位,将校园图像与虚拟校园三维场景构建所需图像进行匹配,由此完成对虚拟校园三维场景的构建。实验结果证明,所提方法是虚拟校园三维场景构建领域革命性的突破,提高了学校的招生率,增加了校园文化历史的展现机会,为该领域的研究发展提供了有效依据。     

Indium-111 labeled bleomycin for targeting diagnosis and therapy of liver tumor: optimized preparation,biodistribution and SPECT imaging with xenograft models

In this work, the preparation of ¹¹¹In radiolabeled bleomycin (¹¹¹In-BLM) was optimized systematically and used for SPECT imaging of liver cancer xenograft models. ¹¹¹In-BLM with a high radiochemical yield (>?99%) could be obtained at pH 0.5–1 at a mixture ratio of 9:1 (¹¹¹In/BLM, mCi/mg). The radiochemical purity of ¹¹¹In-BLM retained?>?99% in either buffers or serum for 3 days. Biodistribution of ¹¹¹In-BLM revealed its excellent stability in vivo. The SPECT imaging studies showed ¹¹¹In-BLM has great specificity to liver tumor xenograft. All the results implied ¹¹¹In-BLM is a potential radiopharmaceutical for targeting diagnosis and therapy of liver tumor.

     

A white noise approach to infinitely divisible distributions on Gel'fand triple

In this note, we apply white noise analysis to infinitely divisible distributions on a real Gel'fand triple E⊂H⊂E^∗. We first introduce an index, called Hida index, for a measure on E⊂H⊂E^∗. And then, under some mild conditions, we obtain a general inequality which indicates a connection between the Hida index of an infinitely divisible distribution on E⊂H⊂E^∗ and that of its Lévy measure. Finally we prove that the Hida index of the standard compound Poisson distribution on E⊂H⊂E^∗ is exactly 1.
