| 摘 要： | 在描叙了On型感受野特性的基础上,结合Bubble函数和负高斯-拉普拉斯二阶微分函数,给出了实用的On型感受野数学模型;探索性地描叙了人眼微动产生中央凹区信息精细处理、周边区域保持适度警觉的机理,据此提出了大尺度On型感受野与小尺度Off型感受野相结合的人眼微动精细处理模型,并利用该模型对红外图像进行了边缘提取,显示出对弱小目标处理的快速性和精确性.

| Abstract: | Firstly this paper discusses the property of On-center receptive field(On-center RF) in detail,then putes forward a applied mathematic model,which integrated Bubble function with the negative second-order derivative of GaussianLaplacian function;a new assume based on vision mechanism is propsed.The information are subtly disposed in fovea and retained moderately watchfulness in para-fovea based on eye microsaccade,so a new combining large scale On-center RF with small scale Off-center RF vision model is pro... |
