- 虚拟仪器代表着目前测试仪器领域的发展方向，LabⅥEw语言是一种功能强大的仪器开发平台。对淹没在噪声中声发射信号的有效提取(去噪)是声发射信号处理技术的第一步，也是声发射信号处理的关键所在。本文介绍了基于小波变换的阈值去噪方法。在LabⅥEw平台上，通过仿真试验，对声发射信号的几种阈值法的去噪结果进行比较，选出一种适合声发射信号去噪的阈值准则。-Virtual instrument on behalf of the current de

- 图象增强 小波变换将一幅图象分解为大小、位置和方向都不同的分量。在做逆变换之前可以改变小波变换域中某些系数的大小，这样就能够洋选择的放大所感兴趣的分量而减小不需要的分量。 给定一个图象信号，用二维小波分析对图象进行增强处理。-Image enhancement will be a wavelet transform image decomposition for size, location and direction of t
