视网膜-视皮层映射模型在红外成像制导系统中的应用研究
首发时间:2004-03-05
摘要:视网膜-视皮层映射是生物主动视觉的生理基础之一,本文以Schwartz提出的log-polar映射模型为基础,结合生物视觉的大小视场系统,提出了一种基于红外成像系统视场角的LPT(log-polar transform)算法,构成了非均匀性的数据采集、传输结构模型,在成像制导信息处理中为解决视场角、分辨率、实时性三者间的矛盾提供了一条途径,本文基于此算法进行了相关验证,显示出利用此算法便于注意力机制在成像制导系统中的实现,并在目标跟踪方面也具有较好的应用前景。

Retino-cortical mapping’s model and it’s application in image-guiding system
Abstract:Retino-cortical mapping is a important attribute of human visual system, which enable human visual system can have the large visual field and high acuity on gaze point simultaneously. The aim of this paper is to use this mapping model in image-guiding system in order to resolve the conflict among “visual field angle”、 “acuity” and “real-time processing”. Based on Log-polar mapping model, this paper put forward a new algorithm of LPT. This algorithm is dependent on the visual field angle, then a non-uniformed data sampling、data transferring module is constructed. With this module, infrared image-guiding information processing system can realize the data reduction, especially in tracking phase. In addition, it facilitates the visual attention system in image-guiding field.
