Abstract

In the recent paper entitled “A robust logo watermarking technique in divisive normalization transform domain” by Pandey et al. [4], a robust digital image watermarking scheme based on divisive normalization transform, discrete wavelet transform and singular value decomposition is proposed. This comment shows that the scheme has watermark ambiguity problem at the detector and could not be used as a proof of ownership application.
