An Adaptive Complex Diffusion Image Denoising Method

Through discussion of the characteristics of complex diffusion, a novel adaptive complex diffusion algorithm based on diffusion parameter k and iterative step Delta t is proposed in this paper. This new algorithm uses the gradient information of image real part to control the diffusion strength and iterative step to achieve better denoising effect in less diffusion time. Numerical experiments results show that this algorithm can remove the noise while preserving more image details and gain higher peak signal noise ratio in a shorter time.
