An Edge Detection Algorithm Based on Short-term Synaptic Plasticity in Gazing Mechanism in HVS
基于人眼视觉注视机制下突触短时可塑性的图像边缘检测算法

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.
