Inpainting Assisted Self Recovery With Decreased Embedding Data
Zhenxing Qian, Guorui Feng · IEEE Signal Processing Letters · 2010
When hiding information in an image for self recovery, the amount of embedding data affects the embedding influence and the recovery quality. The purpose of this paper is to reduce the amount of embedding data while maintaining good recovery quality. We propose an approach to generate reference data from the original image by encoding different types of blocks into different number of bits. In reconstructing the reference image, a fast inpainting method is used to recover the contents of corrupted regions accompanied with the extracted bits.
