Searching trademark databases for verbal similarities
We review various issues related to techniques for searching through collections of trademarks for phonetic and other verbal similarities. Based on recent case studies, we survey judicial arbitrations that have established whether trademarks are similar or not and comment on popular algorithms for performing approximate searches, both phonetically and based on letter sequences. The particularit...
متن کاملShape-Based Retrieval: A Case Study With Trademark Image Databases
Retrieval eeciency and accuracy are two important issues in designing a content-based database retrieval system. We propose a method for trademark image database retrieval based on object shape information that would supplement traditional text-based retrieval systems. This system achieves both the desired eeciency and accuracy using a two-stage hierarchy: in the rst stage, simple and easily co...
متن کاملGestalt-based feature similarity measure in trademark database
Motivated by the studies in Gestalt principle, this paper describes a novel approach on the adaptive selection of visual features for trademark retrieval. We consider five kinds of visual saliencies: symmetry, continuity, proximity, parallelism and closure property. The first saliency is based on Zernike moments, while the others are modeled by geometric elements extracted illusively as a whole...
متن کاملRecent Research on Database System Performance Advanced Research Topics in Databases
Performance of databases highly depend on how data is stored and accessed. It is a challenging task to design a data layout scheme that gives good performance results under different query types and changing workloads when concurrent queries are given to the system. In this report, our aim is to present recent research proposals that aim to overcome performance bottlenecks in databases.
