The paper adapts edge model of convolution between point spread function based on Gauss fitting and ideal edge. The gray distribution of edge pixel is fitted based on the model. Compared point spread function of Gauss with Bessel, the research shows that the effects using Gauss is better than the latter and the value of parameters obtained by Gauss is closer to the given value than the latter.
