In this paper , we first established the image metadata used in our system which based on the famous dublin core , then we analyzed the abstraction and description visual features of image such as color texture and shape . next , we discussed the problem of similarity measure of visual feature , imported fuzzy logic into the distance feature and pointed out the disadvantages of geometry space based methods . for multi - dimension vector ' s high dimension nature , it ' s hard to index with traditional methods , we discussed how to lower the dimension using clustering and klt transformation
本文首先在dublincore的基础上制定了适合我们要求的图像元数据集；详细分析了颜色、纹理、形状等视觉特征的提取和表示方法；探讨了图像视觉特征相似度量的问题，将模糊技术引入直方图的距离度量，分析了几何空间距离度量函数的不足之处，提出了系统中采用的距离函数；针对图像视觉特征向量的多维特性，分析了现有的各种降维技术和多维索引技术。
