“…There are various IVE methods such as Fast Fourier transform-based cross-correlation (FFT-CC), 8 Optical Flow 9 and feature-based IVE methods like feature-based initial guess (FB-IG), 10 path-independent initial value estimation (PI-IVE). 11 Feature-based IVE is considered to be the most robust and efficient approach in providing the initialization values for large deformation due to its invariance to translation, scale, and rotation.…”

“…Moreover, the fewer the detected feature points at a particular region, the higher the probability of mismatched feature points. 9 As a result, more feature points must be computed to achieve densely populated regions of feature points, increasing the computation time. However, several studies have come up with alternatives to deal with the non-uniform distribution of feature points, such as the work conducted by Chi and Pan.…”

“…Moreover, the local continuity is not considered, leading to potential discontinuities in the resulting dense displacement field. To achieve real-time analysis in local DIC, redundant computations have been eliminated [6] and parallel computing [23] has been employed. Therefore, the calculation of the GLR filed, as a post-processing method, should be calculated as fast as possible to avoid becoming the bottleneck of real-time analysis and to complement the efforts made to accelerate DIC calculation.…”
