It includes such operations as contrast enhancement, cropping, scaling, geometric warping, and frequencydomain processing.
它包括的操作有对比度增强、剪切、缩放、几何弯曲和频率范围处理。

This notion of inter-domain transformation is useful in many fields of study-for example, moving from the time domain into the frequencydomain in the field of signal processing.
这种域间转换的概念在很多领域的学习中都很有用—例如，信号处理领域中从时间域移入频率域。

Through collecting vibration signal and analyzing it in the frequencydomain in the condition of changing parameter cutting, a single self power spectrum is hard to detect tool breakage effectively.
