资源说明：Digital image correlation has become an important and effective non-contact optical full-field strain measurement technique. The strain field obtained directly by image correlation algorithm is full of noise. In this letter, we explore a novel way of actively adding small amount of Gaussian random noise to original displacement field, subsequently utilizing the well-known thin-plate spline smoothing (TPSS) technique to smooth the noised displacement field, and finally differentiating smoothed di
