The pipeline image processor produces real-time correlation fringes and allows rapid automatic evaluation of correlograms. On-line operation ...
TheVIC-3D Real-Time processing moduleallows thousands of full-field data points to be displayed live while a test is running. This provides users with the information needed to make critical adjustments during the test, ensuring the loading is applied as expected. ...
Pattern recognition is carried out by a digital image processing procedure which maps a rectangular grid onto the image. The grid points are characterized by three dimensional coordinates and by the gray scale distribution in their proximity. After straining the pattern is again recognized based on ...
