    • Interaction of ON and OFF pathways for visual contrast measurement 

      Neumann, Heiko; Hansen, Thorsten; Pessoa, Luiz
      We propose a novel model of visual contrast measurement based on segregated pathways that are fed by responses from initial ON and OFF center-surround processing. The primary goals of our investigation were to (1) establish ...
    • Visual filling-in and surface property reconstruction 

      Neumann, Heiko; Pessoa, Luiz
      We study the problem of the reconstruction of achromatic surface properties, namely brightness. We show that the filling-in of brightness through a diffusion process can be linked to the general framework of feature ...
