摘要:
One of the most challenging research issues in content-based image retrieval (CBIR) is how to bridge the significant semantic gap between the low-level image features and the high-level semantic concepts. The well-known solutions are relevance feedback and regions of interest (ROIs) detection; however both are subjective and time-consuming. We propose the visual information is a new feature that can objectively interpret the high-level concepts and effectively reduce the semantic gap in image retrieval. We also make a survey on the research progresses and key technologies of visual perception. The research issues of image retrieval based on visual perception are introduced as well from four aspects: ROIs detection, image segmentation, relevance feedback and personalized retrieval.
