This book, "Image and Video Retrieval," comprises the refereed proceedings of the 5th International Conference on Image and Video Retrieval (CIVR 2006), held in Singapore. It presents a vital collection of 18 revised full papers, 30 poster papers, and extended abstracts from a special session and demonstration papers. The volume comprehensively covers cutting-edge research in diverse areas, including interactive and semantic image/video retrieval, visual feature analysis, machine learning for classification, retrieval metrics, and automatic content tagging. As a snapshot of the field in 2006, it serves as an essential resource for researchers and practitioners in computer vision, multimedia, and information retrieval, showcasing the state-of-the-art and future directions.
“Bridging the semantic gap remains a fundamental challenge in image and video retrieval, necessitating advanced learning and inference techniques.”
Key themes
- Semantic Image and Video Retrieval
- This theme explores methods to bridge the "semantic gap" – the disparity between low-level visual features (colors, textures, shapes) and high-level human semantic concepts (objects, events, emotions). Papers under this theme investigate techniques to understand and retrieve visual content based on its meaning rather than just its raw pixel data, often employing machine learning, ontology mapping, and context analysis.
- Visual Feature Analysis
- This theme focuses on the extraction, representation, and robust characterization of visual information from images and videos. It involves developing algorithms for identifying distinctive elements like color histograms, texture descriptors, shape contours, motion vectors, and interest points, which form the basis for comparison and retrieval. The quality of feature representation directly impacts retrieval accuracy.
- Learning and Classification for Retrieval
- This theme covers the application of machine learning techniques to improve image and video retrieval systems. It includes supervised, unsupervised, and semi-supervised learning methods for classifying visual content, training models for semantic concept detection, relevance feedback mechanisms, and adapting retrieval systems to user preferences or specific domains.
