This chapter outlines a computational framework of recurrent processing emphasizing the need and computational role for mechanisms of spatial integration. It argues that in boundary processing, feedback is utilized in order to find the most likely and consistent interpretation of degraded input measurements by assessing and combining contrast items. This computational framework is also proposed to apply for the estimation of coherent motion by integrating local ambiguous flow estimates. It proposes that an extended filling-in mechanism can account for the perceptual integration of partially occluded regions by processes of amodal completion.

Keywords: filling-in; recurrent processing; spatial integration; surface perception; amodal completion; feedback
