Adaptive face coding and discrimination around the average face

Adaptation paradigms highlight the dynamic nature of face coding and suggest that identity is coded relative to an average face that is tuned by experience. In low-level vision, adaptive coding can enhance sensitivity to differences around the adapted level. We investigated whether sensitivity to differences around the average face is similarly enhanced. Converging evidence from three paradigms...

A Construction of Solutions to Reflection Equations for Interaction-Round-a-Face Models

We present a procedure in which known solutions to reflection equations for interactionround-a-face lattice models are used to construct new solutions. The procedure is particularly well-suited to models which have a known fusion hierarchy and which are based on graphs containing a node of valency 1. Among such models are the AndrewsBaxter-Forrester models, for which we construct reflection equ...

SURF-Face: Face Recognition Under Viewpoint Consistency Constraints

Introduction. Recently, a comparative study in [2] has shown the superior performance of local features for face recognition in unconstrained environments. Due to the global integration of Speeded Up Robust Features (SURF) [1], the authors claim that it stays more robust to various image perturbations than the more locally operating SIFT descriptor. However, no detailed analysis for a SURF base...

Analyzing Gaze During Face-to-Face Interaction

We present here the analysis of multimodal data gathered during realistic face-to-face interaction of a target speaker with a number of interlocutors. Videos and gaze have been monitored with an experimental setup using coupled cameras and screens with integrated eye trackers. With the aim to understand the functions of gaze in social interaction and to develop a coherent gaze control model for...
