Method for modifying a reference block of a reference image, method for encoding or decoding a block of an image by help of a reference block and device therefore and storage medium or signal carrying a block encoded by help of a modified reference block
Abstract:
A method for modifying a reference block of a reference image, the method includes transforming the reference block into a first set of coefficients, modifying the first set of coefficients by help of one or more weights and inverse transforming the modified first set of coefficients wherein the weights are determined by help of one or more further pixels of the current image and by help of one or more further reference pixels of the reference image.
Abstract(Chinese):

一种用于修改参考图像的参考块的方法，所述方法包括将参考块变换为第一组系数，通过一个或多个权重的帮助来修改第一组系数，并逆变换修改的第一组系数，其中， 权重通过当前图像的一个或多个其它像素的帮助并通过参考图像的一个或多个另外的参考像素的帮助来确定。
