Semantic clusters based manifold ranking for image retrieval

Ran Chang, Xiaojun Qi
2011 2011 18th IEEE International Conference on Image Processing  
Extensive experiments demonstrate our system outperforms the other manifold systems and SVM-based systems in the context of both correct and erroneous feedback.  ...  Specifically, we apply the SVM-based relevance feedback technique to create semantic clusters for computing the reliability score of each database image.  ...  The remaining 90% of the database images (i.e., the images not used in the training process) are used as queries for all the experiments.  ...

Interactive Trademark Image Retrieval by Fusing Semantic and Visual Content [chapter]

Marçal Rusiñol, David Aldavert, Dimosthenis Karatzas, Ricardo Toledo, Josep Lladós
2011 Lecture Notes in Computer Science  
In this paper we propose an efficient queried-by-example retrieval system which is able to retrieve trademark images by similarity from patent and trademark offices' digital libraries.  ...  Logo images are described by both their semantic content, by means of the Vienna codes, and their visual contents, by using shape and color as visual cues.  ...  In our system, all the trademarks in the database have an associated list of Vienna codes. We can see in Figure 2 a set of trademark images all belonging to the same category.  ...

The Use of Ontology in Retrieval: A Study on Textual, Multilingual and Multimedia Retrieval

Muhammad Nabeel Asim, Muhammad Wasim, Muhammad Usman Ghani Khan, Nasir Mahmood, Waqar Mahmood
2019 IEEE Access  
Ontological information retrieval systems retrieve data based on the similarity of semantics between the user query and the indexed data.  ...  Trivial keyword-based information retrieval systems highly depend on the statistics of data, thus facing word mismatch problem due to inevitable semantic and context variations of a certain word.  ...  In the retrieval process of images, user feeds the system images as an example, these example images are converted into a feature vector and compared with those database feature vector [102] . while the  ...

Ontology of Gaps in Content-Based Image Retrieval

Thomas M. Deserno, Sameer Antani, Rodney Long
2008 Journal of digital imaging  
In particular, we define an ontology of 14 gaps that addresses the image content and features, as well as system performance and usability.  ...  The semantic gap divides the high-level scene understanding and interpretation available with human cognitive capabilities from the low-level pixel analysis of computers, based on mathematical processing  ...  They are formulated in such a way that they can be used in a variety of semantic contexts of medicine, where CBIR systems are applied.  ...
