Imatest Version 26.1

Information-based Dynamic Range (InfoDR)

• The InfoDR target is a two-layer transmissive film chart comprised of 42 patches and 48 slanted edges, with a total density range of 5.2 or 104 dB.


• Enables the measurement of information capacity over a wide range of illumination levels.


• Can be analyzed with Imatest 26.1.4.


• See the white paper: Image Quality Testing Based on Information Metrics

Purchase Chart

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

Stray Light (Flare)

• 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.
