This study proposed an image enhancing method which is based on the non-local fractional order
differential operator. In this method, a matrix form representation of discrete fractional order differentiation is
introduced to enhance the digital image, which is effective to reduce the computation error caused by the traditional
local approximate method of the fractional order differentiation. The proposed enhancing method is able to make
effective use of the whole image information and improve the enhancing performance of the image enhancing
algorithm based on the local mask. The color image enhancing strategy based on the non-local fractional differential
also is given. A lot of experiments demonstrate that the proposed method is capable of enhancing gray and color
image effectively.
Key words: Digital image, fractional differential, image enhancement, non-local, , ,
