| 摘 要： | 给出一种改进阈值算法,与现有的两种算法的消噪效果对比,结果表明,文中提出的改进阈值去噪方法在均方根误差和信噪比意义上均优于已有的两种改进阈值去噪方法,改进公式更为合理。

| Abstract: | A new improved algorithm of threshold value is introduced in the paper,comparing with the two existing improved methods in the effect of noise reduction.The results show that the improved method in the paper is better than existing improved threshold denoising methods in RMSE and SNR,the improved formula is more reasonable. |
