 Filling-In the Forms: Surface and Boundary Interactions in Visual Cortex

This chapter outlines how filling-in may play a key role in surface perception, ranging from lower-level uses, such as recovering surface brightness and color after discounting the illuminant and filling-in the blind spot, to higher-level uses, such as completing depthful modal and amodal surface representations during 3D vision and figure-ground separation. Surface filling-in plays a central role in visual percepts because boundary and surface computations are complementary. Boundaries and surfaces need to interact reciprocally to merge these complementary properties into a consistent visual percept. Boundaries help to trigger depth-selective surface filling-in, and successfully filled-in surfaces reorganize the global patterning of boundary and surface signals via feedforward and feedback signals.
