Abstract
Data storage via multimedia technology is more preferred as the information in multimedia contain rich meanings and are concise when compared to the traditional textual information. However, efficient information retrieval is a crucial factor in such storage. This paper presents a cognitive classification based visual saliency guided model for the efficient retrieval of information from multimedia data storage. The Itti visual saliency model is described here for generation of an overall saliency map with the integration of color saliency, intensity and direction maps. Multi-feature fusion paradigms are used for providing clear description of the image pattern. The definition is based on two stages namely complexity based on cognitive load and classification of complexity at a cognitive level. The image retrieval system is finalized by integrating a group sparse logistic regression model. In complex scenarios, the baselines are overcome by the proposed system when tested on multiple databased as compared to other state-of-the-art models.
