Relevance Feedback in CBIR [chapter]

Hongjiang Zhang, Zhong Su
2002 Visual and Multimedia Information Management  
A new focus in content-based image retrieval (CBIR) research is applying relevance feedback originally developed for text document retrieval, to improve the retrieval performance.  ...  We consider relevance feedback in CBIR a small sample-learning process in sparse image feature space. Almost all of the previously proposed methods fall well into such framework.  ...  By analysing the feature distribution of the segmented regions, a probability association between each segmented regions and annotated keywords is set up for labelled images by region-based relevance feedback  ...

Region-Based Image Retrieval using Radial Basis Function Network

Kui Wu, Kim-hui Yap, Lap-pui Chau
2006 2006 IEEE International Conference on Multimedia and Expo  
This paper presents a new framework that integrates relevance feedback into region-based image retrieval (RBIR) systems based on radial basis function network (RBFN).  ...  A new kernel function of RBFN is introduced for image similarity comparison under region-based representation.  ...  Since different regions in an image have unequal importance for computing image similarity, we propose a probabilistic region weight learning method to capture the relevance of the constituent regions  ...

Efficient search

Alexander G. Hauptmann, Jonathan J. Wang, Wei-Hao Lin, Jun Yang, Michael Christel
2008 Proceedings of the 2008 international conference on Content-based image and video retrieval - CIVR '08  
We introduce an interface for efficient video search that exploits the human ability to quickly scan visual content, after an automatic system has done its best to arrange the images in order of relevance  ...  The system will demonstrate several ways to rapidly scan images, change search queries, and employ different types of relevance feedback.  ...  Thus the system searches video for similar regions to ones specified by the user in a sample query image.  ...
