Description: 龙书。主要介绍如何使用DirectX 9.0开发交互式3D图形程序，重点是游戏开发。全书首先介绍了必要的数学工具，然后讲解了相关的3D概念。其他主题几乎涵盖了Direct3D中的所有基本运算，例如图元的绘制、光照、纹理、Alpha融合、模板，以及如何使用Direct3D实现游戏中所需的技术。介绍顶定点着色器和像素着色器的章节(包含了效果框架和新的高级着色语言的内容)对这些关键运算进行了较为集中的讨论。-Dragon Book. Describes how to use DirectX 9.0 for developing interactive 3D graphics program, focusing on game development. The book introduces the necessary mathematical tools, and then explain the concepts related to 3D. Other topics covered almost all of the basic operations in Direct3D, such as pixel mapping, light, texture, Alpha integration, templates, and how to use Direct3D technology needed to achieve the game. Introduction top spot shaders and pixel shaders chapters (includes results framework and a new high-level shading language content) for these critical operations for a more focused discussion.

Description: Abstract. We present a novel 3D face recognition approach based on
geometric invariants introduced by Elad and Kimmel. The key idea of
the proposed algorithm is a representation of the facial surface, invari-
ant to isometric deformations, such as those resulting from different
expressions and postures of the face. The obtained geometric invariants
allow mapping 2D facial texture images into special images that incor-
porate the 3D geometry of the face. These signature images are then
decomposed into their principal components. The result is an efficient
and accurate face recognition algorithm that is robust to facial expres-
sions. We demonstrate the results of our method and compare it to ex-
isting 2D and 3D face recognition algorithms.

Description: 基于内容感知的低照度图像增强方法，在边缘和纹理区域分析图像对比度得到adhoc变换函数，区分不同的图像特征并模仿人类视觉特征进行分组，针对每一组建立特定的映射函数以增强相应的特征，最后将不同组变换进行混合以实现自适应增强图像细节。-Illumination image enhancement method based on the perception of content, and texture at the edges of the image contrast is adhoc regional analysis transform function, differentiate image features and mimic human visual characteristics are grouped establish specific mapping function for each group to enhance the corresponding feature Finally, the different groups will be mixed to achieve adaptive transform image detail enhancement.
