CBIR
- 本源码是用C++编写的基于内容的图像检索，采用形状、颜色、纹理三个特征的加权值作为特征向量。-The source code is written in c++ of content-based image retrieval, the shape, color, texture three characteristics of the weighted value as the characteristic vector.

- 状是含有高层语义信息的视觉特征，在基于内容的图像检索及图像识别中具有重要的应用价值。有很多种描述子可以描述图像的形状特征，傅立叶描述子可以把二维的图像轮廓信息简化成一维问题进行处理，应用非常广泛。然而自然图像的形状特征通常是杂乱的，有噪声的，提出了一种图像预处理方法，得到净化的形状图像，通过实验研究傅立叶描述子算法提取形状特征的效果。-Abstract Shape is a visual feature which contains intrinsic high-level semantics
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
