摘要 提出一种自适应条纹图像空域滤波方法.该方法能够自动识别条纹图像的不同频率区域.针对低频(稀疏)区域,采用一种新的基于二次曲面拟合的滤波方法进行去噪;对于高频(密集)区域,则先估计条纹空间频率,再利用该频率重新计算像素灰度的最小二乘逼近值,从而达到滤波的目的.该方法适用于各种类型光学条纹图像的降噪处理,特别是空间频率变化较大的条纹图像的处理.实验及计算机模拟结果都证明了该方法的有效性. In this paper, an adaptive filtering algorithm for fringe patterns is presented. The algorithm automatically identifies different frequency regions of a fringe pattern, and adaptively switches between two different filtering methods for low-frequency and high-frequency regions in the pattern. The method is effective in noise reduction for various fringe patterns. It is particularly suited to fringe patterns containing large changes in spatial frequency. Computer simulation and experiment are carried out to demonstrate validity of this method.
