Constrained by the triangle constraint integrated with the conventional epipolar geometric constraint, the local continuity constraint is enforced by changing the constraint areas dynamically according to the local texture density. 3 The topographic structure extraction and analysis based on grid DEMs are investigated in this dissertation, the topographic structure extraction approach fills depressions by adopting vector processes combined with traditional neighborhood raster processes, assigns flow direction over flat by applying a neighbor-grouping scan method.

2提出了一种基于核线影像对和良好匹配点三角形局部连续性约束和顺序约束下的影像匹配方法，该方法利用已知良好匹配点在Delaunay TIN的约束下进行纹理自适应的匹配传播，同时利用新的匹配点对Delaunay TIN进行动态细化使得局部几何约束区域的大小自动适应影像纹理特征的变化，从而得到更加可靠的影像匹配结果。

The use of co-occurrence matrix, texture analysis of image information, for learning image texture information has helped.

This approach was based on the NonSubsampled Contourlet Transform. The means and variables of NSCT coefficients matrix in different subbands and various directions were extracted to form the feature vectors which were regarded as indexes of texture images in image database. Two similarity functions were used to compute the similarity between images. A texture retrieval system based on query image was developed.

该方法利用非下采样Contourlet变换对图像进行分解，提取不同子带和不同方向变换系数矩阵的均值和方差为特征向量，作为数据库中纹理图像的索引，并利用两种不同的相似度函数计算图像之间的相似度，建立了一套基于示例查询图像的纹理图像检索系统。

Anisotropic texture filtering used as a texture magnification or minification filter.

The thesis is based mostly on three recent papers on learning gibbs distributions. They are [Zhu 97]"s work on creating a unified statistical framework by minimax entropy principle, which is then used to learn texture images, [Guo 01]"s proposal for learning the distribution of intrinsic texture element by gibbs model and [Liu 01]s introduction of the minimax Entropy idea to the learning of Inhomogeneous Gibbs Model.

本论文的基本出发点是基于下面三篇关于吉布斯学习的重要文献，即[Zhu 97]中创造的用最小最大熵准则学习纹理图像分布的一套统计框架，[Guo 01]中提到的用吉布斯模型学习纹理基元分布的方法，以及[Liu 01]中介绍的关于非均匀吉布斯模型(Inhomogeneous Gibbs Model，简称IGM)的学习机制。

The same vertex buffers are created (position, normal, texture coordinates, alternate texture coordinates).

创建相同的顶点缓存（位置，法向，纹理坐标，替换纹理坐标）。

For mult-stream single-index rendering, 4 input vertex buffers are created. They store position, normal, textures coordinates, and alternative texture coordinates respectively.

多数据流单索引绘制需要创建4个输入顶点缓存分别保存位置，法向，纹理坐标和可替换的纹理坐标。

Point data is reorganized by generating index list respectively for geometric coordinates, texture coordinates and normal vectors. Triangular facet data is reorganized by collecting the faces with the same material attribute and generating triangle strip. Texture image data is reorganized in the format of DDS.

采用对几何坐标数据、纹理坐标数据和法线向量数据分别建立索引列表的方式重组点数据，通过集中存储相同材质面片和生成三角形条带来重组三角形面片数据，采用DDS图像压缩格式重组纹理数据。

Based on this approach, a hybrid texture segmentation experimental system is designed and implemented, where the OWT is used for realizing the fast image transform.

利用这一系统对典型纹理图象、岩石表面、和航拍市区照片的纹理分割进行了应用研究。
