[Implementation of V1 Area Contour Integration Mechanism and Attention Selection Based on Excitation-Inhibition...

This paper aims to utilize the intersecting cortical model(ICM),which imitates the biological neural cells sync pulse,to preliminary research about the contour integration mechanism and the selection of attention.The idea of"Excitement-Inhibition"oscillation is introduced into the ICM,and meanwhile,the target contour chain code is used as the high-level feedback to control the input.Thus,we propose the Excitation-Inhibition-ICM which contains both the BUTTON-UP and the TOP-DOWN mechanism.The experimental results showed that the proposed model could effectively suppress noise to make the smooth edge synchronization issue,thus completing the process of BOTTOM-UP.The introduction of the target contour chain code can obtain consistent target outline with the input target chain code,but other targets cannot form a closed contour since they do not match with the input target chain code,so as to realize the TOP-DOWN mechanism.The results proved that our proposed model could imitate the contour integration mechanism and the selection of attention of the visual cortex V1.
