Off型感受野研究及在红外图像处理中的应用
THE STUDY OF OFF-CENTER RECEPTIVE FIELDS AND THE APPLICATION FOR INFRARED IMAGE
摘要
论证了感受野(RF)学说和侧抑制(LI)理论的本质一致性.引入医学领域眼球微动现象,在视觉瞬间,指出物象斑将不可避免地交替出现在On型感受野(On-center RF)和Off型感受野(Off-center RF)之间,据此提出了新的视觉机理假说.描述了Off型感受野的特征,并建立描述Off型感受野的数学模型.基于此模型探讨了新的边缘检测算法,应用于**红外图像处理,显示了该算法的快速性以及对目标几何特征的放大能力.
Abstract
The receptive field (RF) theory and the lateral inhibition (LI) mechanism are of the same view.According to the eye′s microsaccade phenomena supported by the medicine field, the proposed opinion states that image spot of object will project the On center RF and off center RF alternatively in the split seconds, so a new vision mechanism′s assume based on this opinion is proposed; this paper discussed the property of Off center RF in detail, and put forward a mathematic model that has a advantage to carry out the edge detecting algorithm, especially to the military IR image, this algorithm posses the characteristics of speeding and feature magnify.
