摘要 在彩色图像检索中,颜色是最重要的特征。论文提出了一种利用多特征向量的彩色图像检索方法。该方法基于HSV颜色模型提取示例图像的颜色特征与图像库中图像的颜色特征时,提取不同维数的特征向量。在图像匹配时对不同维数的特征向量采用不同的距离计算方法,并且通过设置阈值实现分层检索图像数据库。从而提高了图像检索的效率,有效地解决了查询中准确率和效率的矛盾。 In colors image retrieve,the color is the most feature.This paper presents a method by using multi-feature vector to retrieve colors image.The Feature Vector with different dimension is extracted with this method when extract-ing the color feature of the example image and image in database based on HSV color model.And different distance caculation method is used in image comparing,and the image database is retrieved storiedly by set limen.As a result the efficiency of image retrieval is improved.
