DeepRFWT: Approach to mitigate defocus blur effects in DIC-based strain analysis

•DeepRFWT was proposed for defocused speckle image restoration in DIC.•MSFE, MTDED and FDST modules were designed for multi-domain feature processing.•The superiority of DeepRFWT was confirmed by dataset evaluation and mechanical tests. Digital Image Correlation (DIC) technology is confronted with c...
