Digital image correlation (DIC) is a typical non-contact full-field deformation parameters measurement technique based on image processing technology and numerical computation methods. To obtain the displacements of each point of interrogation in DIC. subsets surrounding the point must be chosen in the reference image and deformed image before correlating. In the existing DIC techniques. https://www.ealisboa.com/mega-sale-Sol-Sunguard-Altitude-Sunscreen-1-5oz-big-savings/
