Border-Ownership (BO) selective cell has been reported in early- to intermediate- level visual cortex. A Computational study has suggested that surround modulation underlies this BO selectivity. In a previous study, the model based on surround modulation was applied to 100 natural images (Berkeley Segmentation Dataset), with the result showing
good agreement with human perception. We defined Gestalt Factors (convex and parallel) of contours in natural image quantitatively and compared these factors to model outputs. It was showed that the model tends to determine the Gestalt Factors as Figure. We also carried out a psychophysical experiment in which human subjects had to report Direction of Figure of contours in natural image. Human perception agreed with the model. These suggest that surround modulation is a critical factor for the detection of Gestalt Factors. |
