Imatest Pilot Program

Imatest Version 24.1 Alpha

Imatest 24.1 Alpha is available below

General Improvements

  • Registration Mark Detection: Now includes an alternative machine learning/computer vision (ML/CV) registration mark detection method to aid with automatic target identification and ROI placement. This new detection method is available for the following analyses: Random/Dead Leaves, eSFR ISO 12233:2017, eSFR ISO 12233:2023, Star Chart, 36-Patch Dynamic Range, Contrast Resolution, ISO 14524, and ISO 15739.
  • Improved Handling of DNG files: Added ability to read non-standard bit depth DNG files using direct read option, and Incorporated Adobe DNG SDK into Libraw DNG read option for improved processing according to DNG specification. There is a new dropdown option for the DNG Read method selection in the Options II window, to allow the choice between the original Libraw processing and the new Adobe SDK processing.
  • Checkerboard: Now includes a High-distortion option for checkerboard detection, providing improved detection robustness for highly distorted images.
  • Rescharts and Color/Tone: Now includes the ability to hide the text overlaid on select plots as an option under the Display dropdown, located at the top of Rescharts and Color/Tone Interactive windows.

Image Information Metrics — from slanted edges

  • SNRI and Edge SNRi  (Independent Observer Signal-to-Noise Ratios). Measures of the detectability of objects and edges.
  • Matched filter design  Procedure for designing electronic filters that optimize object and edge detection metrics, SNRi and Edge SNRi.
  • Slanted edge SFR interpolated binning method for reducing spurious high-frequency signals from SFR curves. Reduces sawtooth artifacts in motion blur analysis and improves the reliability of MTF10 measurements, but not recommended for general use because it lowpass-filters the SFR.

Refer to this documentation, for instructions on using the new options for information capacity calculations, and more information on the new measurements.

Stray Light (Flare)

Main Window

  • Now includes the ability to annotate images with Custom Metadata.
  • Now includes improved General Settings search with highlighting.

Known Issues

This is a Beta version of the software, major issues are listed below:

  • Crash occurs when using Registration Mark Detection on a Star Chart
  • eSFRiso charts ROI not auto detected if “machine vision autodetect” selected on SFRreg settings
