摘要 采用高斯型点扩散函数拟合方法与理想边缘做卷积得到边缘模型,基于该模型对黑白棋盘的像的边缘像素灰度分布进行拟合,通过比较高斯型点扩散函数与贝赛尔型点扩散函数的拟合效果,研究表明利用高斯型点扩散函数拟合获得的拟合参数比后者更接近给定的初始拟合参数值,边缘拟合效果更好。 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.
