摘要
通过对数字散斑干涉（ＤＳＰＩ）条纹散斑噪声分布规律的分析，本文提出一种用于ＤＳＰＩ条纹降噪声处理的空域滤波法—复合区域平均法。处理结果表明，该方法不仅处理速度快而且其去噪声效果能与ＤＣＴ方法相媲美。
In this paper, the adaptive visual primitiVe element matched method forunderstanding of interferometrie finges has been developed. By this method, the smooth reStonsin the fringe pattern are determined.Further, by directional derivative,the fringe skeleton maybe obstained accurately.Theoretical analysis,processingprocedure and experimental results arepresented.
