Optoelectronic and Preattentive Vision

在完成某些任务时，生物视觉系统甚至可以胜过最复杂的图像处理系统。本研究的目标是建立光电电路，以类似于生物视觉系统的方式执行一些重要的图像传感和处理任务。这种电路不仅在执行这些任务时比传统方法更有用，而且还为原始生物系统提供了一种分析工具，一种抽象水平。通过提出基于神经膜离子传导基本模型的视觉系统元素，系统地实现了这一目标。演示了每个提议元素的处理能力。接下来，提出了更复杂的任务，可以通过将这些基本元素组合在一起来执行。本文认为，在一个复杂的动态世界中，这种对视觉数据采集的智能控制对于实时操作是必不可少的

In accomplishing some tasks, biological visual systems can outperform even the most sophisticated image processing systems. The goal of this research is to build optoelectronic circuits which perform some important image sensing and processing tasks in a somewhat similar manner to the biological visual systems. The circuits are then not only useful in performing these tasks better than conventional methods, but also provide a tool of analysis, a level of abstraction, for the original biological systems. This goal is methodically pursued by proposing elements of a visual system that are based on a basic model of ionic conduction in nerve membranes. Processing capabilities of each of the proposed elements is demonstrated. Next, more sophisticated tasks are proposed which can be performed by combining these basic elements together. It is argued that this intelligent control of acquisition of visual data is essential for real time operation in a complex dynamic world.//
