Effective Region-based Relevance Feedback for Interactive Content-based Image Retrieval
نویسندگان
چکیده
This paper proposes an effective framework for interactive region-based image retrieval. By utilizing fuzzy coarse segmentation and the graph structure for representing each image, the retrieval process was performed by measuring the image similarity according to the graph similarity. To assess the similarity between two graphs, fuzzy inter relations among regions feature vectors and spatial dispositions as well as fuzzy regions weights are explored. A region-based relevance feedback scheme was also incorporated into the retrieval process, by updating the importance of query image regions based on the user feedbacks, leading to a further performance improvement. Experimental study proves that the proposed region-based relevance feedback mechanism tailors the system semantic behavior relatively to each user personal preferences through the accumulation of the useful semantic information from the feedback information.

Probabilistic feature relevance learning (PFRL) is an effective method for adaptively computing local feature relevance in content-based image retrieval. It computes flexible retrieval metrics for producing neighborhoods that are elongated along less relevant feature dimensions and constricted along most influential ones. Based on the observation that regions in an image have unequal importance...

Relevance feedback and region-based representation of images are two effective ways to improve accuracy in content-based image retrieval. In this paper, we propose a novel relevance feedback approach based on region representation. It can be considered as a special case of the query point movement method in region-based image retrieval. By assembling all the segmented regions of positive exampl...
