Goal-oriented top-down probabilistic visual attention model for recognition of manipulated objects in egocentric videos. Signal Processing: Image Communication, vol. 39, part B, pp. 418–431.0923-5965https://hdl.handle.net/10016/32442We propose a new top down probabilistic saliency model for egocentric video content. It aims to predict top-down visual attention maps focused on manipulated objects, that are then used for psycho-visual weighting of features in the problem of manipulated object recognition. The model is probabilistically defined using both global and local appearance features extracted from automatically segmented arm areas and objects. A psycho-visual experiment has been conducted in a guided framework that compares our proposal and other popular state-of-the-art models with respect to human gaze fixations. The obtained results show that our approach outperforms several popular bottom-up saliency approaches in a well-known egocentric dataset Furthermore, an additional task-driven assessment for object recognition in egocentric video reveals that the proposed method improves the performance of several state-of-the-art techniques for object detection.14eng© 2015 Elsevier B.V.Atribución-NoComercial-SinDerivadas 3.0 EspañaSaliency mapsEgocentric visionObject recognitionVision modellingImage processingVideo processingresearch articleTelecomunicacioneshttps://doi.org/10.1016/j.image.2015.05.006open access418Part B431Signal Processing: Image Communication39AR/0000017605
