| 摘 要： | 介绍了用小波阈值滤波方法实现比色测温信号的滤波消噪.该方法基于信号和白噪声在小波变换下具有不同的特性,将含噪信号进行多尺度小波分解,采用软阈值方法将其高频部分进行量化处理,再进行重构.实验证明该方法有效去除了信号中的噪声,方便地用软件实现了比色测温信号的处理,提高了系统的测温精度.

| Abstract: | Noise elimination of color comparison signal with threshold filtering of wavelet is introduced. This technique is based on the fact that the character of signal and white noise are different during wavelet transform. The signal with noise is decomposed to wavelet of various scales and the section of high frequency is processed in quantity by soft threshold and then reconstructed. The experiment indicates that this technique can remove the noise of signal conduct processing of color comparison signal with software to promote sensitivity of the whole system. |
