This chapter discusses the mechanisms of texture filling-in. With prolonged fixation, targets defined by texture contrast rapidly fade and disappear into the background in a way similar to that of targets defined by brightness, color, and motion. Psychophysical and neurophysiological evidence suggests a two-stage mechanism for the filling-in of figures by their background: Gradual breakdown of the segregation of a figure from its ground is followed by fast filling-in of background features through the region formerly occupied by the figure. These segregation processes comprise both lower-level mechanisms of boundary representation and higher-level attentive and cognitive factors. The chapter proposes that the interpolation processes active during the filling-in of figures by their grounds are similar to the interpolation processes occurring through scotomas and through surface regions in the visual field.
