摘要
Searching interested images based on visual properties or contents of images is a challenging problem and it has received much attention from researchers in the last 20 years. The gap between low-level visual features and high-level semantic understanding of images, which is also known as the semantic gap problem, is the bottleneck to further improvement of the performance of a content-based image retrieval system. In order to solve this semantic gap problem, one of the most popular approaches in recent years is to change the focus from the global content description of images into the local content description by regions (region-based image retrieval) or even the objects in images (object-based image retrieval). Although much research in region-based image retrieval has already been done, there are still three main problems need to be tackled properly: (a) local region-based features, (b) similarity measures, and (c) relevance feedback based on regions. In this paper, we review some recent development in region-based image retrieval with respect to the above three problems and propose some future directions for region-based image retrieval research towards the end of this paper.
