Subpixel Matching Using Double-Precision Gradient-Based Method for Digital Image Correlation
Digital image correlation (DIC) for displacement and strain measurement has flourished in recent years. There are integer pixel and subpixel matching steps to extract displacement from a series of images in the DIC approach, and identification accuracy mainly depends on the latter step. A subpixel d...
