The logo in (a) is blurred by a Gaussian filter, yielding (b). Image (b) appears brighter and more colorful than the original. Using our model, image (c) produces the same color appearance even after the blurring operation. Note that actual pixel values in image (c) are different from the original image (a). |

Abstract |
| |
|
| |
Color perception is recognized to vary with surrounding spatial structure, but the impact of edge smoothness on color has not been studied in color appearance modeling. In this work, we study the appearance of color under different degrees of edge smoothness. A psychophysical experiment was conducted to quantify the change in perceived lightness, colorfulness and hue with respect to edge smoothness. We confirm that color appearance, in particular lightness, changes noticeably with increased smoothness. Based on our experimental data, we have developed a computational model that predicts this appearance change. The model can be integrated into existing color appearance models. We demonstrate the applicability of our model on a number of examples. |
