A Wavelet Inpainting by a Tixotrop Model

Abstract

Image inpainting is a fundamental problem in image processing and has many applications [1] and [2], motivated by the recent tight frame based method on image restoration in either the image or the domain transformation. In this work, we present an inpainting model based on tixotrop non-Newtonian ‡uids [3] for damaged wavelet coe¢cients. The advantage of this model is to make a bene…t from the smoothing model and correct the lying out of the contours by putting them more clearly. Experimental results using our model show that better inpainting quality can be achieved with much less computing time.
