Contour erasure

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right.

Blurry contour is less effective

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right.

Adapting contour must match size of test

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right.

Effect of half adapting contour

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right. (Model predicts stronger erasure than subjects report.)

Dividing line adaptor blends two halves

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right.

Adapting influence on brightness pyramids

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right.

Adapting influence on brightness annuli

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right. (Model does not demonstrate brightness contrast effect. Should be fixable.)

Adapting flicker: Contour must match size of test

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right.

Adapting flicker

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right.

Prediction: Illusory contour does not induce adaptation, so no contour erasure

Stimuli on the left. Model contour signals in the middle. Model filling-in percept on the right.
