Imatest 5.2 has added several new features on top of the major enhancements made in version 5.1. New features include an interface with DevwareX, the ability to process companded images, IEEE P2020 Contrast Detection Probability, and improved dynamic range calculation resistance to flare light.
ON Semiconductor DevwareX
Support for this advanced image sensor interface software, which replaces Devware. APbase image acquisition API is also supported.
Decompanding
Use this option for the proper processing of piecewise linear (PWL) companded RAW files, which can extend sensor dynamic range by allowing different tonal curves for ranges of digital output values.
Contrast Detection Probability (CDP)
Use this option from Contrast Resolution chart using low-contrast path triplets to calculate the draft IEEE P2020 metric. CDP is a metric for the distinguishability from two input light levels through an imaging system.
Improved Color/Tone Module Interfaces
Chart selection is clearer and more robustColor - Tone Setup is the new name for Multicharts (interactive) and Color/Tone Auto is the new name for Multitest (fixed).
Hyperbolic Wedge and Siemens Star analyses
Now supported in Arbitrary Charts.
Dynamic Range (DR) Resistance to Flare Light
We can now detect conditions where flare light causes exaggerated DR measurements and can remedy the misleading measurements by limiting the quality-based DR to the slope based DR, which is defined by the scene density where the patch pixel-level stops decreasing.
INI File Monitor
Produces detailed reference information about the effects of settings changes on the Imatest INI file.
Checkerboard Uniformity Calculations
Produce summaries of nonuniform illumination similar to those produced by SFRplus.
Minor Features
Find sharpest files plot to show focus score metric across multiple images.
Faster bilateral filtering in Image processing module.
Image acquisition Improvements: FLIR camera interfaces, GenICam upgraded, performance improvement for the acquisition of RGB frames, Dalsa Driver Upgrade, ORCA-Flash4.0 camera upgrade
Chart MTF Suitability Display as part of the chart quality calculator, this shows the quality level relative to sensor size and vertical field of view.
Debug Levels offer the ability to control the production error, warning, info, and debug messages.
Bayer Frequency Units - previously when we would analyze a bayer RAW format we would do 4:1 downsampling while retaining the same pixel size. A new option in more settings enables cycles per total pixels or channel pixels to be selected.
Dcraw Updated to Version 9.28 that adds support for Canon EOS 5D Mark IV.
Improve Handling of High Bit Depth RAW and HDR Files by improving the lightening feature during region selection.
Edge Spread Function Plots respect the selected spatial frequency units, previously it would always be in cycles/pixel.
