  • Based on the bjpu - 3d large - scale chinese face database and the correspondence between these faces by though mesh resampling , we have altered the three - dimensional shape and two - dimensional surface reflectance of the original 3d faces by making use of the average face , then we have implemented a series of experiments to measure the contributions of three - dimensional shape and two - dimensional surface reflectance to face image recognition under this change pattern . from the experiment results based on the eigenface algorithm , we concludes that the two types of information are both important for face recognition but the 3d shape is much more important than the 2d surface reflectance , this conclusion gives good suggestions and clues to the design of face recognition algorithms in future
    在本实验室建立的大规模中国人的三维人脸库和基于重采样三维人脸对齐算法的基础上,本文设计合理的实验,采用平均三维人脸来改变原始三维人脸的形状和纹理信息,系统地分析了在这种变换模式下的人脸三维形状和二维纹理对人脸图像识别的影响,在eigenface算法上的试验结果表明,形状和纹理信息对人脸识别都有很大影响,并且形状信息的影响远远大于纹理信息的影响。
  • Measuring method and technique that 3d surface shape is recovered from 2d gray image ( shape from shading ) can obtain surface shape by natural way and easily realize the information integration of intersystem . particularly , this technique belongs to non - contact measurement , and it has become a puzzle and hotspot question in image measuring domain based on vision in recent years
    直接由物体的二维灰度图像恢复其三维几何形状(由明暗恢复形状)的曲面测量方法和技术,能以自然方式提取物体表面的形状信息,且易于实现系统间的信息集成,尤其是该方法属于非接触测量方法,特别适合于测量由弹性模量低的易变形材料制成的零件,近年来一直是基于视觉的图像测量领域研究的难点和热点问题。
  • The method we designed first selects local area with typical object and extracts edge information from these object , then feature points is matched using a criterion combined with edge shape and gray - level information . in such steps , we obtain robust and steady control point using for image registration
    本文描述的方法通过选取图像中的典型区域,利用地物特点提取边缘特征,并利用边缘形状信息和局部灰度统计信息结合作为特征点提取及同名点匹配的判别准则,可得到符合地物性质及直观认识的匹配特征点。
  • Considering the shape expression modes are more diversiform , dispersed , and complex in shop drawing , many notations in shop drawing contain shape information , also with distinct characteristics , a new method of extracting engineering quality based on notation entities functional semantics is put forward in chapter 5
    建筑图样形体形状的表达方式丰富、多样,建筑图样的很多标注中蕴涵形体的形状信息,并且这些标注具有明显的视图特点。论文第五章通过分析施工图中的标注和建筑物功能部件的关联特征,提出了基于标注实体功能语义的工程量信息获取方法。
