EXTENDED GABOR FUNCTION MODEL AND SIMULATION OF SOME CHARACTERISTIC CURVES OF RECEPTIVE FIELD

In this paper we propose a family of extended Gabor functions as weight functions of the primary information processing in the visual system. The orientation tuning curve, the length tuning curve and spatial frequency tuning characteristics of simple cells, complex cells and some hypercomplex cells were simulated by means of our model. The results calculated by this model coincide closely with the experimental data. It has been shown that the extended Gabor function model can reasonably describe the main properties of receptive fields several levels of the visual system.     

广义Gabor函数模型和感受野某些特性曲线的模拟

本文提出用一族广义Gabor函数作为视觉系统初级信息加工的权函数,对视皮层的简单细胞、复杂细胞和某些超复杂细胞的取向调谐曲线、长度调谐曲线和空间频率调制曲线进行模拟计算,取得良好结果。本文认为广义Gabor函数模型能较好地描述视觉系统各级水平上感受野的主要性质。
