Imagine a visual world of random blotches of colour and texture, like an abstract painting. This is a world without shape, and it illustrates how our capacity to see structure and recognize objects is determined by our ability to perceive shape. In the proposed project we will employ a novel combination of psychophysical and computational methods to determine how the human brain extracts and represents 2D and 3D shape information from contours in complex imagery, and will develop improved computer vision algorithms for object segmentation and shape processing based upon these insights.

想象一个由随机的颜色和纹理斑点组成的视觉世界，就像一幅抽象画。这是一个没有形状的世界，它说明了我们看到结构和识别物体的能力是如何由我们感知形状的能力决定的。在拟议的项目中，我们将使用一种新的心理物理和计算方法的组合来确定人脑如何从复杂图像的轮廓中提取和表示2D和3D形状信息，并将基于这些见解开发用于对象分割和形状处理的改进的计算机视觉算法。
