Imatest plans to implement Colorchecker SG autodetection in a future release. Note that we will not perform autodetection for the Obsolete ISO 12233:2000 target because it can easily produce invalid results.

The best experience with Imatest comes when it can automatically detect targets. This allows for tests to be automated and improves the efficiency and repeatability of your testing workflow (see following sections).

A typical green laser pointer has a beam diameter of around 3mm and a divergence of 1.2mRad. So: 3+(1.2*2000)= a spot size of 2403mm (2.4m) by ...

Users can choose to Skip Refinement Step for registration mark detection. This may help with failing regmark detection at the cost of less accurate localization.

Starting in Imatest version 24.1, users can choose between the default registration mark detection and an alternative machine learning/computer vision (ML/CV) registration mark detection with a tunable confidence threshold. This new setting can be accessed from the Imatest Master main window choosing Settings, General Settings, then navigating to the settings for a particular target via the analysis groupings.
