Abstract
This paper presents a new image contrast enhancement method based on the complex Ensemble Empirical Mode Decomposition (EEMD) and alpha-rooting approaches. The new scheme also takes advantage of Fourier transform properties and complex Intrinsic Mode Functions (IMFs). The experimental results show that the images obtained by this combination are more appealing than the best results yielded by classical alpha-rooting technique. This algorithm is tested on the medical images, hazy aerial images and other low contrast images.
