摘要
Abstract
Image sharpness evaluation function based on gradient calculation is widely used in automatic focus system, and these functions vary in form. In this paper, starting from the mathematical principles of image gradient calculation, with simulation experiments under MATLAB, performance of common gradient class evaluation functions was compared and analyzed, and methods combining the characteristics of imaging system to control the performance of these algorithms are presented.关键词
