摘要

作为一种自适应的相似度度量,引入了签名二次形式距离,以应对各种多媒体数据的灵活内容表示。尽管特征二次型距离在检索的有效性和效率方面表现出了良好的性能,但由于其动态特性,其在索引结构中的适用性仍然是一个具有挑战性的问题。本文研究了基于度量访问方法的签名二次型距离的可索引性。我们展示了距离的固有参数如何决定可索引性,并分析了在众多图像数据库中有效性和效率之间的关系。

Indexing the signature quadratic form distance for efficient content-based multimedia retrieval
The Signature Quadratic Form Distance has been introduced as an adaptive similarity measure coping with flexible content representations of various multimedia data. Although the Signature Quadratic Form Distance has shown good retrieval performance with respect to their qualities of effectiveness and efficiency, its applicability to index structures remains a challenging issue due to its dynamic nature. In this paper, we investigate the indexability of the Signature Quadratic Form Distance regarding metric access methods. We show how the distance's inherent parameters determine the indexability and analyze the relationship between effectiveness and efficiency on numerous image databases.
