| Abstract: | Digital watermarking techniques have greatly developed in recent years. Watermarking techniques based on the transformation domain has become a heated issue in the academic research of the field. In this pager an adaptive digital watermarking technique in the DCT domain is proposed. Experimental results demonstrate that this kind of algorithm has good effect with invisible watermark and good robustment. |
