DIC Course Data processing 1

Data processing 1: Simulated speckle images (duration : 4h00)

Objectives

• Learn how to use the MatchID 2D software

• Process simulated images

• Understand the effect of spatial resolution (without noise) by playing with subset size.

• Understand the effect of noise on displacements and strain.

• Understand the effect of smoothing on resolution and spatial resolution ( strain window dimensions)

Competencies

• The trainee knows how to process images in a DIC system and is familiar with concepts as subset size, step size and strain window size.
