摘    要:在基于内容的图像检索中,颜色特征已得到广泛应用.本文对十种利用颜色特征进行图像检索的算法利用同一图像库进行了实验比较.实验结果表明,无论在HSI空间或MTM空间,累加直方图法均优于一般直方图法,对这一点本文还首次给出了严格的理论证明.实验结果还表明,加权距离法比欧氏距离法总体上没有明显改善,MTM空间比HSI空间也没有显出优势,而中心矩法算法简单,检索速度快,通过调整加权系数,检索精度可以接近累加直方图法.本文的实验和分析对选择和优化检索算法有一定的参考价值.

关 键 词:图像检索  累加直方图  彩色空间  欧氏距离

Abstract:In content-based image retrieval,color features are widely used. This paper reports a comparativesstudy of ten algorithms using images of a common database. The experimental result shows that whether in HSIor in MTM color spase the cumulative histogram based algorithm is much better than the traditional histogrambased algorithm, a mathematical prove is aJso trovital for the first time. the results the show that MTM colorspase has no apparent advantage over HSI color space and using weighted distance as the similarity measure isjust a little better than using Euclidean distance. Ih addition, the results show that the algorithms based on Centralmoments are not only simple but also comparable in performane with the algorithms based on coummulativehistogrm by suitably adapting the weighing coefficients. This work would be helpful for selecting and optimizingretrieval algorithms.
Keywords:Image Retrieval Cumulative Histogram Color Space Euclidean Disstance
