Camera motion influence on dynamic saliency central bias

Saliency models have been extensively studied for static images and the focus is now on moving images. There is a central bias in both cases that is emphasized in the dynamic case. One aspect in this latter is the camera motion that influences the scene interpretation. The movie director exploits this motion to make the observer focus on the targeted object which is often in the center of the scene. This aspect is not taken into account in current saliency dynamic models. In this paper, we study the camera motion influence on the gaze distribution in order to include it in a new saliency model. Observers' gazes are recorded with an eye tracker, camera motions (e.g. tracking, zoom ...) are calculated thanks to a polynomial projection of the motion field and the motion influence is statistically tested on the recorded gazes.
