This paper proposes a new approach for image noise reduction using partial diffusion equation (PDE). Diffusion coefficient is an important parameter in PDE for image noise reduction. This parameter affects the noise reduction results and quality of edges in the denoised image. The existing PDE-based image denoising techniques experimentally adjust the diffusion coefficient. This paper proposes a new approach to adaptively adjust the diffusion coefficient. The proposed approach was applied on a number of standard images to evaluate its performance. The results indicate that the proposed approach outperform the existing PDE-based image denoisng techniques.
