Secondly, based on the optical knowledge such as edge spread function > line spread function and point spread function etc. , motion-blurred point spread function can be assessed through knife-edge function curve, according to the motion-blurred image.
其次，本文在刃边函数、线扩散函数、点扩散函数及光学传递函数等光学知识的基础上，通过检测运动模糊图像的刃边函数曲线，直接由运动模糊图像估算出运动模糊点扩散函数，提高了运动模糊点扩散函数的估算精度。
