Perceived relative depth from velocity gradients: a model.
The effectiveness of velocity gradients in determining the accuracy of perceived relative depth in a translating surface has been shown to depend on the translation speed and the observation time. The organization of the texture elements into a perceived surface and the perception of an illusory rotational component in the motion of the surface also appear to affect accuracy. A model is presented that incorporates these four variables. Predictions of the model are compared to results obtained by Braunstein and Andersen (1981).
