| 摘 要： | 根据视觉信息加工过程中视皮层细胞非经典感受野对中心感受野区域具有抑制作用的生物机制,提出了一种模拟该机制的模型.用Gabor能量作为感受野响应,以高斯差分函数为基础构造两个具有方向的半椭圆环来作为非经典感受野区域,设计中心感受野与周边抑制区域的相位差权重函数来模拟非经典感受野的抑制机制.实验结果与这种生理特性相一致.

| Abstract: | According to the biological mechanism of non-classical receptive field inhibition in the visual cortex while visual infor-mation processing, a new model to simulate the mechanism is proposed. With Gabor energy as a response of receptive field, a non-classical receptive field of region can be modeled by two ellipsoid semi-circle with direction based on the difference of Gaussians function, the weight function has been designed by difference of phase between centre receptive field and the surrounding inhibiti... |
