| Abstract: | A new digital watermarking algorithm for 2-dimensional engineering graphics is proposed based on the principle of fractional S transform. In order to improve the cropping resistant competence of the algorithm, Vectors are overlapped by groups according to finite covering positions, and the watermark is embedded respectively on diverse positions＇ fractional S transform spectrum of vertex set. Experimental results show that the algorithm is robust and safe, effective especially against cropping. |
