据人眼视觉在外界刺激下引发神经细胞突触短时程可塑效应而造成感受野结构发生形变的生理现象，对视觉感受野的形变方式进行了假设，在研究了形变后感受野模型长轴和边缘方向的夹角对滤波效果影响曲线的基础上，提出了一种新的高通滤波算法。通过实验验证了该算法在高通滤波效果和实时性能方面的优越性和文中假设的合理性。结果表明，该算法更加适合于对人眼视觉注视机制的描述。

According to the mechanism that the Short term Synaptic Plasticity caused by repeating stimulation can lead to distortion in receptive fields of neurons in human vision system, a hypothesis on the manner of distortion in receptive fields is proposed in this paper. The influences of the angle of edges orientation and the distorted receptive fields’ long axes on the filtering performance have been studied. Based on the analysis of the curve, a new high pass filtering algorithm is put forward. The experiments confirm the superiority of the algorithm in filtering performance and in real time processing. And the hypothesis mentioned above is proved to be rational in the experiments. The experimental results show that the algorithm is more appropriate to describe the gazing mechanism in Human vision System.
