Abstract

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

Key words: lossless data hiding, self-embedding, inpainting, error concealment
