如何跨越图像低层视觉特征到高层语义特征的“语义鸿沟”已成为语义图像检索问题的关键,首先将待分类图像分成五个区域;然后在提取图像底层特征的基础上,采用基于支持向量机组(SVMS)的方法建立图像低层视觉特征到高层语义特征之间的映射,将一幅图像同时归入一类或几类图像语义。实验结果表明,该方法具有较好的检索查全率和准确率。
The solution of "semantic gap" which existence between the low-features and the high-level semantic features had become the key in problems of the semantic image retrieval, First separated the image into five part, then extracted low-level features, used a new approach to establish a link from image low-level feature to high-level semantic based on support vector machines. Finally, the images were classified as one or several classes. The experiment proves that it has obtained the high accuracy.
