Author :
Choi, Yoon-Hee ; Choi, Tae-Sun
Abstract :
A new logo embedding scheme that is designed for JPEG coding is presented. A parent-child structure of the DCT coefficients in a block is utilized to embed a watermark with maximum strength and minimal perceptibility. A calculation of an optimum a posteriori threshold is also presented for watermark detection.
