Abstract

The Oriented Difference of Gaussian (ODOG) filter of Blakeslee and McCourt has been successfully employed to explain several brightness perception illusions which include illusions of both brightness-contrast type, for example, Simultaneous Brightness Contrast and Grating Induction and the brightness-assimilation type, for example, the White effect and the shifted White effect. Here, we demonstrate some limitations of the ODOG filter in predicting perceived brightness by comparing the ODOG responses to various stimuli (generated by varying two parameters, namely, test patch length and spatial frequency) with experimental observations of the same.

摘要

布莱克斯利和麦考特提出的高斯方向差分（ODOG）滤波器已成功用于解释多种亮度感知错觉，其中包括亮度对比类型的错觉，例如同时亮度对比和光栅诱导，以及亮度同化类型的错觉，例如白色效应和移位白色效应。在此，我们通过将ODOG对各种刺激（通过改变两个参数，即测试斑块长度和空间频率生成）的响应与相同刺激的实验观察结果进行比较，来证明ODOG滤波器在预测感知亮度方面的一些局限性。
