上述定理应用于复杂背景下的路面检测，结合直方图均衡化算法消除背景噪声；

The method is used to detect actual complex surface, and denoise background noise combined with the histogram equilibrium algorithm.

该技术的一个突出优点是在具有背景噪声的全息测量情况下，可以消除背景噪声对全息变换结果的影响。

A particular feature of the technique is that the influence of background noise on reconstructed results can be removed while retaining the background noise in the holographic measurements.

语音增强的主要目的有两个：一个是改进语音质量、消除背景噪声，使听者乐于接受、不感觉疲劳，这是一种主观度量；

It has two main aims: one is to improve the audio quality, eliminate the background noises, and make the listener feel less tired but more willing to listen, and this is a subjective measurement.
