Comparative Study of Fractional Order Derivative Based Image Enhancement Techniques
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 2
Abstract
In this paper, image enhancement based on fractional gradient is proposed. The Taylor’s Series is used to obtain a generalized expression for this Fractional order derivative. The Image is differentiated in both x and y directions separately. Next, the Gradient is calculated which is nothing but an edge detection operation. For proving, that the proposed approach has better brightness and contrast it is compared to Grunwald – Letnikov fractional differential approach enhancement. The results obtained have shown good performance.
