Abstract:

Gray concurrence matrix and invariant moments were developed to extract texture and shape features in image retrieval. With the relevance feedback mechanism, users could not only control the retrieval procedure, but also obtained satisfying retrieval results by adjusting relevance weights. The experiment shows that the proposed algorithm is effective and can achieve better results.

Key words:  texture, gray concurrence matrix, shape, invariant moments, relevance feedback

摘要：

综合图像的纹理和形状特征进行图像检索时,采用了基于灰度共生矩阵的纹理特征提取 和基于不变矩的形状特征提取方法,并在此基础上加入了基于权重调整的相关反馈机制,使用户可以 参与检索过程,通过调整权重使得检索结果最终满足用户的检索要求。实验表明,这种算法获得了较 好的检索结果。
