DENOISING AN IMAGE BY DENOISING ITS CURVATURE IMAGE By
In this article we show that when an image is corrupted by additive noise, its curvature image is less affected by it, i.e. the PSNR of the curvature image is larger. We conjecture that, given a denoising method, we may obtain better results by applying it to the curvature image and then reconstructing from it a clean image, rather than denoising the original image directly. Numerical experimen...

متن کاملImage denoising using mean curvature ∗
We propose a new variational model for image denoising, which employs mean curvature information of the image surface (x, f(x)) induced by the given image f : Ω → R. Besides removing noise efficiently and preserving edges of objects, our method can also keep corners of objects as well as grey-scale intensity contrasts of images. We also compare our model with the classical ROF model [18].
متن کاملA New Shearlet Framework for Image Denoising
Traditional noise removal methods like Non-Local Means create spurious boundaries inside regular zones. Visushrink removes too many coefficients and yields recovered images that are overly smoothed. In Bayesshrink method, sharp features are preserved. However, PSNR (Peak Signal-to-Noise Ratio) is considerably low. BLS-GSM generates some discontinuous information during the course of denoising a...
متن کاملImage Denoising Using Mean Curvature of Image Surface
Abstract. We propose a new variational model for image denoising, which employs the L-norm of the mean curvature of the image surface (x, f(x)) of a given image f : Ω → R. Besides eliminating noise and preserving edges of objects efficiently, our model can keep corners of objects and greyscale intensity contrasts of images and also remove the staircase effect. In this paper, we analytically stu...
