查询词典 normals

By using techniques from robust statistics, we obtain the approximations of the underlying surfaces. This leads to a conceptually good local patch with precise geometry properties, and as a result, the influence of noises is reduced. In addition, we also present a diffusion method to smooth the geometry properties, including principle curvatures and Frenet frame. The method ensures that the surfaces are smooth in the curvature space, and maintain the details, features and optimize the normals. The results show that, even in a high level noise situation, our algorithm can remove noise effectively, and at the same time keep the details of the model.

与传统的双边滤波去噪算法不同，该算法通过引入鲁棒统计理论获得模型表面较为准确的几何属性；进而在曲率空间中对包含主曲率和Frenet标架的表面几何属性进行各向异性的滤波，既有利于保持模型的细节，又能保证曲面的光滑性；与此同时，优化各个顶点的法向；最后在优化后的几何属性引导下，在几何空间中进行高阶双边滤波去噪。

By means of uniform orthogonal sampling, we represent the shape signature of each model as a statistical distribution of its surface normals weighted by view-dependent depth. The distribution is further processed by spherical harmonics analysis to construct the final representation. By calculating the distance between shape descriptors of individual 3D models, a faithful similarity measurement is achieved.

Methods Monocytes in peripheral blood were obtained from 12 patients with acute myocardial infarction, 16 unstable angina pectoris, 12 stable angina pectoris and 8 normals by ficoll density gradient centrifugalization. The cells were incubated for 48 hours to induce them to differentiate into macrophages by adding phorbolester 12-myristate 13-acetate. The levels of MMP-9 and TF in the supernatant were measured by ELISA.

Blood samples were drawn during different time after onset of chest pain in 60 patients with UA, 30 patients with stable angina pectoris and 30 patients with acute myocardial infarction. Blood was sampled only once per person in 30 normals. CKMM subbands were detected by the nonserial buffer electrophoresis method,and CK as well as CK-MB by velocity method. Student′t test was used for statisical analysis.
