Relevance Feedback for Keyword and Visual Feature-Based Image Retrieval
In this paper, a relevance feedback scheme for both keyword and visual feature-based image retrieval is proposed. For each keyword, a statistical model is trained offline based on visual features of a small se...

Query Clustering in the Web Context
Query clustering is a class of techniques aiming at grou** users’ semantically related, not syntactically related, queries in a query repository, which were accumulated with the interactions between users an...

A visual attention model for adapting images on small displays
Image adaptation, one of the essential problems in adaptive content delivery for universal access, has been actively explored for some time. Most existing approaches have focused on generic adaptation with a v...

Alternating Feature Spaces in Relevance Feedback
Image retrieval using relevance feedback can be treated as a two-class learning and classification process. The user-labelled relevant and irrelevant images are regarded as positive and negative training sampl...

Motion Pattern-Based Video Classification and Retrieval
Today′s content-based video retrieval technologies are still far from human′s requirements. A fundamental reason is the lack of content representation that is able to bridge the gap between visual features and...

Learning in Region-Based Image Retrieval
In this paper, several effective learning algorithms using global image representations are adjusted and introduced to region-based image retrieval (RBIR). First, the query point movement technique is consider...

A systematic rate controller for MPEG-4 FGS video streaming
This paper proposes a systematic rate controller (SRC) for content-aware streaming of MPEG-4 FGS video over the Internet. An active layer drop** technique is proposed to provide both coarse-grain and fine-g...

Motion-Based Video Representation for Scene Change Detection
In this paper, we present a new framework to automatically group similar shots into one scene, where a scene is generally referred to as a group of shots taken place in the same site. Two major components in t...

Improving Image Retrieval with Semantic Classification Using Relevance Feedback
In this paper, we investigate the combination of image semantic classification with content-based image retrieval. A flexible scheme is proposed to take advantage of image classification, which may be obtained...

A New Shot Boundary Detection Algorithm
Shot is often used as basic unit for both analyzing and indexing video. In this paper, we present an algorithm for automatic shot detection. In our algorithm, we use a ‘flash model’ and a ‘cut model’ to deal w...
