Pseudo Relevance Feedback Based on Iterative Probabilistic One-Class SVMs in Web Image Retrieval
نویسندگان
چکیده
To improve the precision of top-ranked images returned by a web image search engine, we propose in this paper a novel pseudo relevance feedback method named iterative probabilistic one-class SVMs to re-rank the retrieved images. By assuming that most top-ranked images are relevant to the query, we iteratively train one-class SVMs, and convert the outputs to probabilities so as to combine the decision from different image representation. The effectiveness of our method is validated by systematic experiments even if the assumption is not well satisfied.

Document Image Retrieval Based on Keyword Spotting Using Relevance Feedback
Keyword Spotting is a well-known method in document image retrieval. In this method, Search in document images is based on query word image. In this Paper, an approach for document image retrieval based on keyword spotting has been proposed. In proposed method, a framework using relevance feedback is presented. Relevance feedback, an interactive and efficient method is used in this paper to imp...
متن کاملEvaluation of Kernel Based Methods for Relevance Feedback in 3d Shape Retrieval
Relevance feedback in information retrieval is an iterative search technique to bridge the semantic gap between the high level user intention and low level data representation. The main motivation for this work is that there is very little research done on applicability of relevance feedback methods to 3D shape retrieval. We experimentally evaluate 4 state-of-the-art techniques stemming frommac...

Content-based image retrieval (CBIR) has received considerable research interest in the recent years. The basic problem in CBIR is the semantic gap between the high-level image semantics and the low-level image features. Region-based image retrieval and learning from user interaction through relevance feedback are two main approaches to solving this problem. Recently, the research in integra...
