An Image Enhancement Algorithm Based on Fractional-Order Relaxation Oscillator

In this paper, a cortex rhythms mimicking in fractional-order Relaxation oscillator is implemented and the existence of the rhythm is proved. Furthermore, the Quasi Gamma Curve (QGC) model is established based on the fraction-order Relaxation oscillator in the rhythm oscillation and we certify that the property of QGC model is similar to that of Gamma Curve by curve fitting methods. The proposed model is utilized to enhance the low contrast images. Different quantity measures demonstrate that the proposed model is effective.
