Custom Metadata
Custom Metadata adds the ability to annotate your image files with extra information. Attributes can be defined and organized to suit your unique requirements. For example, you can log chart distance, lighting conditions, device details, or just free form text notes. This information can be easily viewed and edited in Image Preview.
Image Information Metrics from slanted edges
Image Information Metrics is expanded from what was released in 2023:
- 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 is not recommended for general use because it lowpass-filters the SFR.
Stray Light
- Maximum measurable stray light calculation. The maximum measurable stray light is the stray light that corresponds to one digital number less than the saturation. It represents the worst stray light value that the test configuration is capable of measuring. This metric is useful when comparing results between two different test setups.
- Counting of the number of saturated pixels per analysis frame.
- Support for ITU-R BT.709-6, ITU-R BT.2020-2, and MATLAB luminance calculations.
Machine learning/computer vision (ML/CV) Registration mark detection
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.
General Improvements
- Checkerboard: adds High-distortion option for checkerboard detection, providing improved detection robustness for highly distorted images.
- Rescharts and Color/Tone: adds 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.
- Color/Tone and Stepchart: The functionality of the saturation level setting has been modified to allow for better handling of images with nonstandard bit depth or saturation level offsets.
- Main window: improved General Settings search with highlighting.
