Description
Summary:Image enhancement is an important part of image processing, affected by the process of image acquisition, transformation, transmission, etc., the image quality will be reduced, the subsequent processing will be limited by the problems. Based on the characteristic of texture enhancement and noise suppression, fractional differentiation operation has been used in image processing, since it can not only strengthen the high and middle frequency components of the signal, but also can preserve the low frequency components. The paper designs an improved image enhanced operator based on the combination of fractional differentiation and interpolating operation called the maximum of interpolating operation fractional differentiation (MIOFD). Experiments show that the texture and edges of the images processed by MIOFD are enhanced. The enhancement is better than the integer differentiation, compared with traditional fractional differentiation, our method can preserve non-node pixels information and enlarge the difference of details, also makes the enhancement better.
