Learning and Intelligent Systems: Intelligent Visual Grouping: Basic Mechanisms, Models, and Applications

IBN-9720305 PI：沙普利这个项目由学习与智能系统倡议提供资金。这些问题涉及中枢神经系统的视力和学习。该项目调查了大脑如何表示和处理感知信息，以及当系统学习和提高其性能时发生的适应性变化。在这里，视觉系统被用作进入大脑工作的门户，采用了心理物理学、神经生理学、数学和工程学的方法。这项工作的重点是视觉分组，这是视觉系统将视觉图像的局部元素链接到一致的整体的能力。分组是人类视觉最基本的方面之一，本工作的目标是获得一种能够解释生理和心理物理数据的视觉分组理论，并将新的技术思想应用于智能人工系统。结果将是重要的，因为理解大脑中产生分组的计算将是我们对大脑功能以及任何能够适应经验的系统的理解的飞跃。因此，这项工作将对设计学习材料和呈现信息的最佳方法以及下一代计算机视觉系统和智能控制系统的设计产生影响。该项目得到了国家自然科学基金会数学与自然科学局多学科活动办公室的部分支持。

IBN-9720305 PI: SHAPLEY This project is being funded through the Learning & Intelligent Systems Initiative. The questions involve vision and learning in the central nervous system. The project investigates how the brain represents and processes perceptual information, and the adaptive changes that occur when the system learns and improves its performance. Here the visual system is used as a gateway into the workings of the brain, employing methods from psychophysics, neurophysiology, mathematics and engineering. The work focuses on visual grouping, which is the ability of the visual system to link together local elements of the visual image into coherent wholes. Grouping is one of the most fundamental aspects of human vision, and the goal of this work is to obtain a theory of visual grouping that will explain the physiological and psychophysical data, and lead to new technological ideas to be applied in intelligent artificial systems. Results will be important because understanding the computations in the brain that produce grouping would be a leap forward in our understanding of brain function, and of any systems that can adapt to experience. This work will therefore have an impact in designing learning materials and in the optimal methods of presenting information, and in the design of the next generation of computer vision systems and intelligent control systems.
