Abstract In this paper, a bioinspired neural model for detecting object motion based on retina computational machanism is proposed based on synthesizing representative works on modeling retina and incorporating some latest findings on retina mechanisms. To understand more in-depth the retina machanism of motion detection, the spatio-temporal properties of each type of neurons in the retina motion pathway are then mathematically analyzed. And then a set of experiments and quantitative analysis of the experimental results are accomplished for assessing the model performance on motion detection. Experimental results show the effectiveness of this proposed model on detecting object motion. Index Terms retina neural mechanism, retina neural network, object motion detection, computational model.
