Biological Information Technology & Systems - BITS: Fixational Eye Movements in Biological and Artificial Vision Systems

EIA-0130851 Rucci，Michele Boston Univ.BITS：生物和人工视觉系统中的注视眼动概述拟议的研究项目有两个目标：（1）确定小眼动对大脑中视觉信息表示的具体贡献，以及（2）将此类机制输出到机器视觉系统。为了实现这些目标，该项目将把神经群体的计算机建模、机器人实验和心理物理实验与人类受试者结合起来，以分析自然观看条件下神经活动的统计结构。这项研究将首先描述在自然观看条件下眼球运动对丘脑和皮层细胞空间选择性的影响。然后，神经元合奏的活动动力学将进行研究，无论是在视觉表征的效率和空间视觉处理的层次结构的心理物理学研究的结果。最后，我们将分析可能参与的小眼球运动的距离信息的恢复在双目自由观看的三维场景。研究将具有双重目的，即提供对大脑的新见解，并考虑机器视觉系统的可能应用。

EIA-0130851Rucci, MicheleBoston Univ.BITS: Fixational eye movements in biological and artificial vision systemsSummaryThe proposed research project has two goals: (1) to determine the specific contributions of small eyemovements to the representation of visual information in the brain, and (2) to export such mechanismsto machine vision systems. To accomplish these goals, this project will integrate computer modeling ofneural populations, robotic experiments and psychophysical experiments with human subjects to analyzethe statistical structure of neural activity under natural viewing conditions. The proposed research will first characterize the influences of eye movements on the spatial selectivity of thalamic and cortical cells during natural viewing conditions. Then, the activity dynamics of neuronal ensembles will be studied, both in terms of efficiency of visual representation and in relation to the results of psychophysical studies on the hierarchical structure of spatial visual processing. Finally, we will analyze the possible involvement of small eye movements in the recovery of distance information during binocular free-viewing of a 3D scene. Studies will be conducted with the dual purposes of providing new insights on the brain and considering possible applications to machine vision systems.
