| 摘 要： | 在介绍滤波去噪基本原理和干涉图去噪质量评价指标基础上,采用整体去噪法和分解去噪法2种方法对干涉图进行滤波去噪实验,并对实验结果进行定性和定量分析研究.结果表明,整体去噪法在图像保真,相位平滑程度效果较好,分解去噪法在抑制斑点噪声影响、图像边缘保持能力接好.

| Abstract: | Based on introducing the basic principles of filtering denoising and interferogram denoising quality evaluation idex,the qualitative and quantitative analysis of the results was carried out by the overall denoising and the decompositive denoising filter denoising interferogram.It was shown that the overall denoising had smoothess of better phase and the decomposition method could suppress speckle noise denoising effect and took a good edge retention. |

| Keywords: | overall denoising decomposition denoising qualitative evaluation quantitative evaluation interferogram |
