Rhythm oscillation in fractional-order Relaxation oscillator and its application in image enhancement

作者：

Highlights：

•

• The limit cycles in fractional-order relaxation oscillator with different external stimuli are discussed.

• The rhythmic oscillations in fractional-order Relaxation oscillator are implemented.

• The Quasi Gamma Curve (QGC) model to enhance images is proposed.

• The QGC model provides better performance than other similar models.
