Image error concealment base on lossless self-embedding
基于无损自嵌入的图像修复方法

This paper presents an image error concealment method using lossless self-embedding.JPEG image was downsampled and halftoned to binary image,which was embedded into the low & middle DCT coefficients using the lossless data hiding method.When data were extracted,original image could be recovered losslessly,and a lowquality image was reconstructed from the hidden data using inverse halftoning and upsampling.Errors on the image could be concealed with the low-quality image.
