experimental results and theoretical analysis has proved the feasibility because of less permissible error of data caused by the embedding of watermarking.
水印嵌入引起的数据误差较小,算法具有较好的可行性。
laboratory simulations and on site tests show that this method is practicable for on line calibration within engineering permissible error range under definite conditions.
it was the first time to take the maximum permissible error as the major specifications of the crustal deformation observation instrument in compiling the seismological industry standard.
