Additional linearization options for eSFR ISO & SFRplus

Dynamic Range Postprocessor

Produces results similar to IEEE P2020 (draft) noise standard. Described in A review of IEEE P2020 noise metrics
Now supports sensor dynamic range calculations from multi-image exposures from HDR sensors.

MacOS 14 Sonoma Support

Main Window Improvements

Stray Light

Supports the IEEE-P2020 pre-release flare attenuation calculation. Our next-generation light source, scheduled for late 2023/early 2024, will meet the uniformity requirements for accurate calculation of flare attenuation. Imatest recommends P2020 (draft) normalized stray light calculation with our current Stray Light LED Light Source.
Ability to normalize with a reference image of a Lambertian diffuser.
Ability to choose output data transforms including linear, logarithmic, and decibel.
Ability to subtract off a dark level.
Ability to have level count summary metrics expressed as a percentage.
Ability to select an analysis channel including: RGB, Each Channel, Mean, and Luminance.
Improved visualization of masked pixels in colormapped metric images.
Now includes the minimum measurable stray light in results.
