International Conference on Intelligent Information Hiding and Multimedia Signal Processing
TL;DR: This study presents a robust and semi-blind watermarking by embedding information into low frequency AC coefficients of Discrete Cosine Transform (DCT) by utilizing the DC values of the neighboring blocks to predict the AC coefficient of the center block.

Variance-Classified Capacity Watermarking Using Discrete Cosine Transform
TL;DR: This study presents a robust and semi-blind watermarking by embedding information into low frequency AC coefficients of discrete cosine transform (DCT) and watermark embedding in the original AC coefficient (WEOAC).
