| titleOfInvention | A kind of evaluating method for geodata watermarking algorithm |
| abstract | The invention discloses a kind of evaluating method for geodata watermarking algorithm: first choose polytype, multiple use, multi-scale, different pieces of information amount, different accuracy geodata as benchmark dataset.Then according to the robustness appraisal procedure of the integral area definition attack resistance degree of watermark accuracy-attack amplitude curve.Finally from data fidelity performance before and after topological relation between precision, atural object and shape three aspect quantitative evaluation embed watermarks.Except These parameters, also have watermark capacity and travelling speed two indices.The last comprehensive evaluation index formulated realizes testing scheme.Therefore, the method can realize fairly and reasonably evaluating and testing watermarking algorithm under the same conditions. |
