Contrast-based image attention analysis by using fuzzy growing
A feasible and fast approach to attention area detection in images based on contrast analysis is proposed and a practicable framework for image attention analysis is presented, which provides three-level attention analysis, i.e., attended view, attended areas and attended points.

MRBIR first makes use of a manifold ranking algorithm to explore the relationship among all the data points in the feature space, and then measures relevance between the query and all the images in the database accordingly, which is different from traditional similarity metrics based on pair-wise distance.
A generic framework of user attention model and its application in video summarization
A generic framework of a user attention model is presented, which estimates the attentions viewers may pay to video contents, and a set of modeling methods for visual and aural attentions are proposed.

A robust approach that is capable of classifying and segmenting an audio stream into speech, music, environment sound, and silence is proposed, and an unsupervised speaker segmentation algorithm using a novel scheme based on quasi-GMM and LSP correlation analysis is developed.
A user attention model for video summarization
A generic framework of video summarization based on the modeling of viewer's attention is presented, which takes advantage of computational attention models and eliminates the needs of complex heuristic rules inVideo summarization.
