A Fast Error Concealment Using a Data Hiding Technique and a Robust Error Resilience for Video
TL;DR: This paper develops temporal and spatial error resilient video encoding and data hiding approach to facilitate the error concealment at the decoder and shows that proposed method conceals properly and effectively burst errors occurred on transmission channel like Internet.

Improved differential energy watermarking for embedding watermark
TL;DR: In this paper, the adaptive differential energy watermarking (ADEW) with cross binding wavelet tree (CBWT) was proposed to improve the robustness of the watermark.
Proceedings ArticleDOI
On the noninvertibility of adaptive digital watermarking
TL;DR: This paper is intended to demonstrate that the widely researched adaptive watermarking is noninvertible in nature if it can induce and exploit the perturbation in an attacker's reverse engineering properly and shows a promising way of making a publicWatermarking scheme, which is considered intrinsically invertible, noninverted.
Journal ArticleDOI
Video Watermarking With Digital Signature and Fingerprinting
TL;DR: In this paper , the authors make use of singular value decomposition (SVD) and discrete wavelet transform (DWT) for video watermarking; the authors employed inverse transform (IDWT) to extract the video watermarks.

Secure spread spectrum watermarking for multimedia
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.
Journal ArticleDOI
Techniques for data hiding
TL;DR: This work explores both traditional and novel techniques for addressing the data-hiding process and evaluates these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.

A digital watermark
TL;DR: The paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512/spl times/512 intensity image with an 8 bit gray scale, capable of carrying such information as authentication or authorisation codes, or a legend essential for image interpretation.
Journal ArticleDOI
Image coding based on a fractal theory of iterated contractive image transformations
TL;DR: The author proposes an independent and novel approach to image coding, based on a fractal theory of iterated transformations, that relies on the assumption that image redundancy can be efficiently exploited through self-transformability on a block-wise basis and approximates an original image by a Fractal image.
