TLDR
A new algorithm based on the discrete wavelet transform to embed readable watermarks into grayscale images is proposed, which is blind, i.e., the embedded watermark is extracted without any reference to the original image.Abstract:
A new algorithm for digital image watermarking is proposed. The algorithm is based on the discrete wavelet transform to embed readable watermarks into grayscale images. In order to increase the algorithm's robustness and ensure the watermark's integrity, error correction coding techniques are used to encode the embedded watermark. The proposed algorithm is blind, i.e., the embedded watermark is extracted without any reference to the original image. Experimental results demonstrate the low watermark perceptibility and the high algorithm robustness against several common image-processing operations.read more

Readable watermarking algorithm based on wavelet tree quantization
TL;DR: Experimental results show that the proposed algorithm is effective and robust to common image processing operations and to some geometric operations, such as JPEG compression, JPEG2000 compression, filtering, adding Gaussian noise and row-column removal, so a conclusion can be made that the suggested technique is practical.

Adaptive watermarking scheme using biased shift of quantization index
TL;DR: A watermark embedding and extracting method for blind watermarking that performs embedding of a watermark bit by shifting the corresponding frequency transform coefficient to a quantization index according to the value of the watermarks bit, which prevents from losing the watermark information during the data compression process.

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.
