A study on advancing color and receding color (chromostereopsis) from a viewpoint of the modified model of longitudinal chromatic aberration.

色立体视指的是一种现象，即如果红色物体位于同一正面平行平面上，则红色物体会出现在蓝色物体的前面或后面。这种现象通常用横向色差模型来解释。然而，该模型在解释色立体视的许多方面存在各种困难，例如半遮挡效应。在此，我们提出了一个部分基于纵向色差模型的新模型，并命名为“重心”模型。我们发现这个模型可以最好地解释色立体视。此外，我们还发现了与我们的模型相关并与之一致的新颜色错觉。

Chromostereopsis refers to a phenomenon that a red object appears to in front of or behind a blue one if they are located on the same frontoparallel plane. This phenomenon is frequently explained with the transverse chromatic aberration model. There are, however, a variety of difficulties for the model to explain many aspects of chromostereopsis, e.g. the half-occlusion effect. Here we have proposed a new model partly based upon the longitudinal chromatic aberration model and named the "center-of-gravity" model. We have found this model to give the best explanation of chromostereopsis. Moreover, we have discovered new color illusions that would be relevant to and agree with our model.
