Effect of positions of lines on the perception of the Ebbinghaus angular illusion
J Uchida, S Ishizaki
The Ebbinghaus angular illusion (tilt illusion) is a basic illusion which relates to line directions or angles between lines. We conducted a psychophysical experiment and found that perception of such illusions is also affected by positions of lines which consist of a basic line and a line moving on the basic line. In addition, a simulation model of V1 in the brain, based on the physiological findings, has been constructed to find a neural architecture which invokes the phenomena. The neurons of this model have inhibitory connections with other neurons whose receptive fields are often different from presynaptic neurons. By using these inhibitory connections, outputs of our model can explain the results of the psychophysical experiments. This model will be useful for constructing a visual architecture with high quality in the near future.
