【摘要】 针对基于内容的图像检索系统检索效率不高的情况,从目标图像外轮廓特征的提取、图像外轮廓特征的描述方式、图像轮廓的语义描述方式和相似度测定4个方面对基于内容的图像检索的研究状况进行了分析和研究。综合图像的外轮廓特征及轮廓的语义描述来实现对图像数据库的检索。实验结果表明,该方法提高了图像检索的精度和效度。更多还原

【Abstract】 To improve the efficiency of image retrieval based on the content,a new method is proposed using the feature extraction of figure,the description of figure features,the description of semantic information of images and the measurement of similarity degree.Achieves the retrieval of image database by combining the characteristic of out contour and semantic description.The experiments show that this method improves the precision and efficiency of image retrieval.更多还原
