Sight-reading of violinists: eye movements anticipate the musical flow

Wurtz, Pascal ; Mueri, René M. ; Wiesendanger, Mario

When sight-reading a piece of music the eyes constantly scan the score slightly ahead of music execution. This separation between reading and acting is commonly termed eye-hand span and can be expressed in two ways: as anticipation in notes or in time. Previous research, predominantly in piano players, found skill-dependent differences of eye-hand span. To date no study has explored visual...

Motion integration in visual attention models for predicting simple dynamic scenes

Bur, Alexandre ; Wurtz, Pascal ; Muri, Rene M. ; Hügli, Heinz

In: Human Vision and Electronic Imaging XII (Proceedings of SPIE), 2007, vol. 6492, no. 47, p. 649219- 649229

Visual attention models mimic the ability of a visual system, to detect potentially relevant parts of a scene. This process of attentional selection is a prerequisite for higher level tasks such as object recognition. Given the high relevance of temporal aspects in human visual attention, dynamic information as well as static information must be considered in computer models of visual attention....

Dynamic visual attention: competitive versus motion priority scheme

Bur, Alexandre ; Wurtz, Pascal ; Muri, Rene M. ; Hügli, Heinz

In: Proceedings. International Conference Computer Vision Systems (ICVS), 2007, p. 1-10

Defined as attentive process in presence of visual sequences, dynamic visual attention responds to static and motion features as well. For a computer model, a straightforward way to integrate these features is to combine all features in a competitive scheme: the saliency map contains a contribution of each feature, static and motion. Another way of integration is to combine the features in a...
