| Abstract: | It is proposed to use Energy Gradient as evaluation fuction of digital image ,which is important to defecting image definition. The mathematical models for evaluation fuction , which characterize the preferable efficiency, have more high signal-to-noise, better reliability , powerful unimodality than other ones. It can be well applied to definition evaluation fuction of image. |
