Digital image correlation and tracking is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This method is often used to measure full-field displacement and strains, and it is widely applied in many areas of science and engineering. Compared to strain gages and extensometers, the amount of information gathered about the fine details of deformation during mechanical tests is increased due to the ability to provide both local and average data using digital image correlation.

- La corrélation d'images numériques (digital image correlation ou DIC en anglais) est une méthode optique 2D ou 3D qui permet de mesurer les déplacements entre deux images. Elle est de plus en plus employée en sciences des matériaux pour déterminer des champs de déformations, détecter des fissures ou pour fournir des champs de déplacements à des procédures d'identification de propriétés matériaux.

- La correlazione digitale di immagini o correlazione di immagini digitali, spesso nota con l'acronimo inglese DIC (Digital image correlation), è un metodo ottico basato sull'analisi di immagini digitali al fine di ottenere misure 2D e 3D di spostamento e deformazione delle superfici, o in generale degli oggetti, presenti nel campo inquadrato. Rispetto a tecniche di misura basate su trasduttori di spostamento e deformazione (estensimetri), che forniscono misure di tipo puntuale, la DIC permette di ottenere simultaneamente informazioni su un numero elevato di punti in una regione di interesse, ossia consente misure di campo (discreto) delle quantità di interesse. Un ulteriore vantaggio di questa tecnica è la caratteristica di non prevede il contatto tra lo strumento e il misurando. (it)
- Корреляция цифровых изображений (англ. digital image correlation and tracking, (DIC/DDIT)) — оптический метод, используемый в техниках отслеживания и идентификации изображения для точных плоских и объёмных измерений изменений на изображении. Этот метод часто используется не только для измерения деформаций, полей перемещений и оптических потоков, но и широко используется во многих областях науки и инженерного ремесла. Одно из наиболее широкоизвестных применений данного метода — идентификация перемещений оптической мышки. (ru)
