An image denoising method based on partial differential equations
Shen Lixinb · Journal of Dalian Maritime University · 2010
An integrated image denoising model was proposed based on total variation(TV) and the fourth-order partial differential equations(PDEs) denoising models to remove noises effectively.The model overcomes blocky effect which is inherent in the TV denoising model,while avoids the uneven phenomenon in the smooth region which is inherent in the improved fourth-order PDEs.Simulation results show that the fidelity of the image is improved a lot.
