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。
It includes such operations as contrast enhancement, cropping, scaling, geometric warping, and frequency domain processing.
对于强剪切变形流动，可以通过设定较小的图像采样时间间隔以提高测量范围。
The time interval of image sampling should be shortened to increase the measurement ranges for higher shearing distortion flows.
加之，剪切散斑干涉条纹灵敏度具有可调性，加载范围大为加宽。
An adjustable sensitivity characterized by the shearing fringe itself will additionally broaden the loading range greatly.
