A New Blind Image Watermarking of Handwritten Signatures using Low-Frequency Band DCT Coefficients
TL;DR: This paper deals with a new blind technique for robust image watermarking in the DCT domain based on embedding watermark information in eight low-frequency band coefficients of the D CT sub-blocks.

A New Blind Image Watermarking Technique for Dual Watermarks Using Low-Frequency Band DCT Coefficients
TL;DR: A new blind robust watermarking technique for embedding two watermarks into a host image based on embedding watermark information in sixteen low-frequency band coefficients of the DCT sub-blocks is proposed.
