It's obvious that semantic retrieval is more reasonable than retrieval based on low features. So we need to study image retrieval based on region segmentation, image hierarchical classification and image semantic label standard.

显然语义级检索是比基于低层特征检索更合理的图像检索方法，因此有必要研究基于区域分割的图像检索、基于语义级的图像分级分类和图像的语义标记标准。

This paper proposed a new algorithm for eyes detection in the images. First, in a known face image, the homomorphic filter was used to enhance the contrast of the image and the iterative thresh choosing algorithm changed the gray images into binary ones. According to certain priori knowledge, it could get the candidate field of the eyes.

提出了一种新的图像中人眼检测算法，在一幅已知的人脸图像中首先采用同态滤波算法增强图像的对比度，然后利用迭代式阈值选择法对图像进行二值化处理，根据传统的先验知识获得眼睛的候选区域。

Finally three representative features are picked up, difference sum of the characteristic crack image projection in horizontal and vertical direction, as well as the pixel number of crack sub image.

基本思想是首先将二值化后的裂纹图像进行分块处理，得到一个特征裂纹图像，最后提取三个具有代表性的特征：特征图像在水平方向和垂直方向上的投影的差分累加和Ph，Pv以及裂纹子图像像素总数Num。

The method comprises the following steps of : respectively constructing models of residual images of a multi-spectral image and a panchromatic image by using hypercomplex, and respectively subjecting the hypercomplex residual models of the multi-spectral image to hypercomplex symplectic decomposition along the grayscale axis direction to obtain a simplex portion containing brightness information and a perplex portion including chromaticity information.

该方法首先用超复数分别对多光谱图像和全色图像的残差图像建模，并对多光谱图像的超复数残差模型沿灰度轴方向分别进行超复数symplectic分解，得到包含亮度信息的simplex部分和包含色度信息的perplex部分。

In the knowledge system of human civilization, language is our main tool of intelligent source and communication, while image is in the awkward condition of shifting and hesitation, and in the incessant attack and elimination due to social ideologies, for example, iconoclasm is a kind of negative oppression and eradication of worldly religious images, which aims not at hoping image becomes the worldly stuff that might affect the divine belief and refuses image is the symbol of divine supremacy.

在人类文明的知识体系中，语言是我们主要的知识来源和交流工具，而图像则处于漂移、犹豫的尴尬处境，不断因为社会意识形态需要而成为被攻击、被消灭的对象，如偶像破坏运动就是对世俗宗教图像的一次否定性压制和根除，目的是不希望图像成为影响神性信仰的世俗物品，拒绝图像是神性至上的象征。

Iconology ::::Image, Text, Ideology .

To make an attempt at constructing the iconography of Akshobhya and the Five Buddhas and discussing the transition of Akshobhya from Mahayana to Vajrayana especially in Tibet, the methodology both of Archaeology, Iconography, Iconology, Religion and History are involved in this thesis. The related images are belongs to the 7th to 15th century.

本文主要采用考古学以及图像志和图像学的研究方法，结合历史、宗教背景，尝试建立阿閦佛及相关密教五佛的图像志，探讨阿閦佛从初期大乘诸神之一到密教五方佛之一的演变，以及其在藏传佛教中的发展，图像资料上下限为7-15世纪前后。

The part of hardware includes mainly the module of image acquisition, the module of video A/D, the module of image buffer, the module of interface logic control, the module of image processing based on DSP and the module of power management. The hardware modules accomplish the image acquisition, digitization, buffer and processing.

硬件部分主要包括图像采集模块、视频A／D模块、图像数据缓冲模块、接口逻辑控制模块、基于DSP的图像处理模块和电源管理模块等，实现了图像信号的采集、数字化、缓冲和处理。

Image segmentation is the fundamentals of image analysis,and threshodling method is an important approach and is widely applied in image processing and recognizing because of its simplicity,fastness and stability.

图像分割是图像分析的基础，阈值法因简单、快速和稳定而成为图像分割的一种重要方法，在图像处理与识别中广泛应用。

This technique has good properties with security, imperceptibility and high hiding capacity of the hidden information.

4基于混沌序列的图像信息隐藏技术；将需要隐藏传送的图像以混沌噪声的形式加入到载体图像的时空变换谱中，接收者根据混沌序列的相关特性利用相应的混沌噪声来提取所隐藏的图像，该技术具有良好的信息安全性、不可觉察性和较高的隐藏容量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
