基于概念分布进行检索是实现图像语义检索的方法之一.提出了基于概念分布的图像语义标注与检索方法.该方法首先对图像概念区域进行编码,在此基础上对概念区域进行标注.检索时用户可通过提交概念所在大概位置信息快速查找出与检索意图相近的图像.设计实现了图像语义标注与检索系统,证实了该方法的可行性.
传统的基于内容的视频检索是刺用图像的颜色、纹理以及形状等底层特征来对视频进行检索,然而这些底层特征并没有深层次地挖掘[1]出视频的语义内容.在用支持矢量机对图像进行分类的基础上,提出了一种基于贝叶斯网络的对视频静态语义如室内/室外进行探测的新方法,实验结果验证该方法的有效性.
提出了一种基于四叉树的动态LOD优化方法.基于多分辨率地形模型的四叉树构建过程,首先钎对四叉树优化采用的3个判断标准--包围体剔除、背面剔除和屏幕投影误差分别进行相应的网格优化,然后在LOD地形中漫游时,随着视点移动而呈现出的不同细节程度的需要,建立了合适的节点评价函数,并在LOD简化过程中根据节点分割和渲染的规律,提出合适的裂缝消除算法,去掉四叉树中不合理的分割,最后使得分割后的节点达到最优以完
In this paper,an adaptive spatial clustering method is presented for automatic brain MR image segmentation,which is based on a competitive learning algorithm-self-organizing map(SOM).We use a pattern
For wavelet transform,a set of orthogonal wavelet basis aims to detect the localized changing features contained in microarray data.In this research,we investigate the performance of the selected wave
A personalized emotion space is proposed to bridge the "affective gap" in video affective content understanding. In order to unify the discrete and dimensional emotion model, fuzzy C-mean (FCM) cluste
Speaker variability is an important source of speech variations which makes continuous speech recognition a difficult task.Adapting automatic speech recognition(ASR) models to the speaker variations i
隐喻在信息可视化系统中有着普遍和广泛的应用。从隐喻视角设计出可视化系统的三个特征维:隐喻喻体、隐喻本体和可视化变量,并对1995-2008年出现的13个典型的信息可视化系统从三个维度进行比较分析。认为从可视化技术发展的长远看,仍然会以文本可视化、社会可视化为主。时间隐喻和空间隐喻是可视化隐喻中最常见、最基本的两类。选取合适的源域和喻体表示时间和空间概念,能创造最佳的可视和交互效果。构建隐喻模型能辅
A low power digital operational transconductance amplifier(OTA) was developed for low voltage switched capacitor applications.The OTA has a high slew rate(SR) and a large open loop gain with a differe
This paper describes the design of a unified framework for a multilingual text-to-speech(TTS) synthesis engine-Crystal.The unified framework defines the common TTS modules for different languages and/
