- The indexing of an image database is often referred as feature extraction. Mathematically, a feature is an n-dimensional vector, with its components computed by some image analysis. The most commonly used visual cues are color, texture, shape, sp
NSCT
- 1．分析研究了基于内容的图像检索系统的工作原理，关键技术如：纹 理、形状等图像底层特征的描述方法， 图像间的相似性度量方法， 图像库索引机制等。 2．研究了基于纹理特征的图像检索方法，并提出了一种基于NSCT 变 换的纹理特征提取方法。通过对SAR 图像及相关图像进行NSCT 分解，计算不同尺度不同方向上的系数幅度序列的均值，标准方差 和三阶中心矩，以此构成特征向量来描述图像的纹理。实验证明本 文提出的采用NSCT 算法有较好的特征提取效果，引入三阶中心矩 作为特

- Query by content, or content-based retri has recently been proposed as an alternative to text-based retri for media such as images, video and audio. Text-based retri is no longer appropriate for indexing such media, for several reasons. Firstly
