【摘要】 采用二进小波变换消除了等离子体激光干涉图象的噪声。分别介绍了利用简单阈值裁剪法与相关系数裁剪法对仿真干涉图的处理结果。研究表明 ,由于分别利用了干涉图象中背景噪声特征以及噪声在不同尺度表征下的非相关性。二者均能消除噪声 ,且后者更为有效。更多还原

【Abstract】 The noise of plasma laser interferogram is removed with binary wavelet transform.The processed results of the simulation interferogram obtained with simple threshold cutting method and correlation coefficient cutting method are introduced,respectively.The study shows that since the background noise characteristics of the interferogram and uncorrelativity under the different scale characterizations are applied,both methods can remove noise,and the later is better.更多还原
