Imatest 26.1 | Imatest

Checkerboard Local Magnification

Checkerboard analysis enhanced to calculate local magnification and related metrics based on Q.Wang et al. 2016
Quantifies how magnification varies across the image field
Provides deeper insight into lens distortion beyond a single global distortion metric
Models the relationship between object and image radii
Computes both radial and tangential magnification variations
Outputs distortion plots, projection classification, corrected images, and data for further analysis

Geometric camera model masking: with the OpenCV Fisheye, Brown-Conrady, pinhole & radial distortion
Easily use the same reference image detection settings as analysis image mask settings.
Analyze a single color channel.
Keep all connected components in image processing masking.

Color/Tone CCE Summary Metrics: JSON/CSV results now includes the mean color contrast enhancement (CCE) from all patch pairs.
Flatfield nonuniformity with respect to center ROI: JSON/CSV results now includes the uniformity of the side and corner regions relative to the center region, as a percentage (0-100).

License Manager: New Offline Deactivation workflow and general stability improvements.

Color Science: Now includes the ability to use Display P3 (D65) luminance weights.
Imatest IT is now compatible with .NET framework 9.0
