Image segmentation and the perception of lightness and color

几乎一半的大脑参与解释视觉信息，这为人类（和许多其他物种）提供了有关外部世界的最详细、最精确的信息。 尽管我们的大脑很容易从视觉信息中确定世界的结构和属性，但这是一个极其困难的问题。 其中一个最基本的问题涉及理解大脑如何确定物体的感知颜色，尽管物体嵌入的照明和大气条件（如烟雾或雾）发生了巨大变化。 这项研究将为视觉系统如何解决这一重要问题提供有价值的见解。

Almost half of the brain is involved in interpreting visual information, which provides the most detailed and precise information about the external world for humans (and many other species). Despite the great ease with which our brains determine the structure and properties of the world from visual information, this is an extremely difficult problem. One of the most basic issues involves understanding how the brain determines the perceived color of objects, despite drastic variations in the illumination and atmospheric conditions (such as smoke or fog) in which objects are embedded. This research will provide valuable insight into how the visual system solves this important problem.
