Abstract :
A novel method for watermark casting using mathematical morphology is presented. Ternary (three-value) signals, as suitable morphological patterns, are applied for digital image watermarking. The watermark is embedded in the spatial domain. The effectiveness of this approach as a benchmark is tested. It is proved that with proper selection of the proposed watermark, the probability of error in the detection will tend to be zero. The proposed method is very easily applied and very fast from the computational standpoint.
