In this paper, a new fractional differential mask has been designed based on improved interpolation operation. Improved Fractional differential mask which called the mean of the fractional differential interpolation algorithm. Firstly, the new operator not only makes the numerical calculation more accurate and converges faster, but also it has better anti-rotation ability. Experiment showes that the enhancement of is better than that of the traditional fractional differential, such as Sobel operator and Laplace operator. Secondly, the new operator can not only enhanced the high-frequency and intermediate-frequency components, but also keep the low-frequency components. Finally, quantitative analysis was adopted on the average gradient, information entropy, contrast and homogeneity, which is judgment index. It shows that the new operator can not only enhance the texture detail information of the image, but also preserved the non-node pixels' information in this study.
