This paper considers the semantic gap in content-based image retrieval from two aspects: (1)
irrelevant visual contents (e.g. background) scatter the mapping from image to human perception; (2) unsup...
Previous web image re-ranking approaches usually construct similarity measure on image level. Considering the diversity of large scale web image database, these approaches ignore the
difference of im...
Effective and Efficient Object-based Image Retrieval Using Visual Phrases
Object-based Image Retrieval Visual Phrases
<
2010/12/16
In this paper, we draw an analogy between image retrieval and text retrieval and propose a visual phrase-based approach to retrieve images containing desired objects. The visual phrase is defined as a...
In the area of image retrieval, post-retrieval processing is often used to refine the retrieval results to better satisfy users’requirements. Previous methods mainly focus on presenting users with rel...
