October 10, 2022

New Features:

Stray Light Analysis Feature – Imatest analyzes images of a bright light source and calculates the stray light for each image. The included stray light metrics in Imatest 22.2 are Point Source Rejection Ratio (PSRR) and unnormalized stray light. The primary output of the analysis are stray light metric images which quantify the amount of stray light in the input images. Other outputs include light source mask files, various summary statistics in standard output formats, as well as colormapped plots and videos. This feature is a step towards defining and supporting next-generation stray light analysis within IEEE-P2020 and ISO.
Auto Exposure measurements in Color/Tone – Given a video input file with a changing light level, this feature will measure the time a camera system takes to adjust the exposure of a scene. Metrics calculated: Temporal Video Analysis – Mean Normalized Pixel Level, Exposure Error, and CPIQ Exposure Quality Loss.
Auto White Balance measurements in Color/Tone – Given a video input file with changing color temperature, this feature will measure the time a camera system takes to adjust the white balance of a scene. Metrics calculated: Correlated Color Temperature.
Compare two images for 3D (stereo imaging) compatibility in Focus Field – Compare the geometry of two images using the Focus Field Post-processor.
Enhanced Image Preview – Enabling zoom and pan with rubber band selection, coordinates display, and minimap.

Imatest Master version 22.1.2 provides a utility to migrate the settings for blemish and uniformity in the INI file to Flat field settings.

If you have been using Uniformity, or Blemish in pre-22.1 Imatest versions, and you wish to migrate your current settings to Flat field settings, you should use this procedure. If you wish to use the default Flat field settings, no action is required.

This migration utility can be run from the new Imatest main window, or from the Classic UI. Directions for running the utility both ways are given below.

- Via New main window

1. Choose any image uniformity file
2. Choose Flatfield interactive
3. Click the Analyze button
4. On flatfield analysis window, choose “INI File Settings” -> “Update from pre-22.1 INI”, and confirm that you want to migrate settings. Prior to migration, a backup is taken of the current ini file.

- Via classic imatest

1. Select flatfield interactive
2. Press cancel when asked to select an image
3. On flatfield analysis window, choose “INI File Settings” -> “Update from pre-22.1 INI”, and confirm that you want to migrate settings. Prior to migration, a backup is taken of the current ini file.

More about this migration utility:

Settings will be migrated over from the previous Uniformity and Blemish sections, to create the Flatfield settings. In the case of conflicting settings, Blemish settings will be given priority. The migrated settings will be saved in the current INI file. As part of settings migration, a log file will be created that lists which settings were migrated, and if there were any conflicts. The backup and log files will be located in the folder where your ini file is located. You will receive a message at the end of migration that gives the exact name and location of the log and backup files.

Features

Lighting Control — Set up and control DMX lights (Kino Flo) and Lightboxes as well as monitor lighting conditions with an Isolight puck directly from Imatest using tools specifically designed with image quality testing in mind. This feature enables you to manage the brightness and color temperature of individual lights and save your settings to scenes which allows you to perform rapid switching between light configurations.
Shannon Information Capacity — Measure the Shannon information capacity of imaging systems in units of bits per pixel from sinusoidal Siemens star patterns. Because frequency-dependent signal and noise are measured from the same locations on the star, they are subject to identical image processing, unlike slanted-edge MTF and flat patch-based noise measurements. Details in The white paper, “Camera information capacity: a key performance indicator for Machine Vision and Artificial Intelligence systems“

Minor Features

New CCM Linearization Option — Calculate the linearization parameters from the grayscale patches on the target. Results are more accurate than previous methods. (The previous Color Correction Matrix [CCM] calculation, derived from images of color charts [including grayscales], generally required knowledge of the gamma [Opto-Electric Conversion Function] curve of the image for proper linearization.)
MATLAB Compiler Runtime Library — Add Mac OS Catalina Support, decrease build size.
Read Raw module updates:
- decompanding JSONs now accept a simpler “kneepoint form” definition.
- 14-bit MIPI unpacking now available.
- 32-bit image data can now be written out.
Software Analytics – This helps us understand the usage patterns of license holders. When you opt in to share usage data with us, we can learn which areas of the software are used most often, which will help us improve our support and offer new licensing options.

Decompanding – 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) – 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 robust.
Color/Tone Setup is the new name for Multicharts (interactive).
Color/Tone Auto is the new name for Multitest (fixed).
Hyperbolic Wedge and Siemens Star – analyses are now supported in Arbitrary Charts.
Dynamic Range (DR) Output 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.
Image Statistics Mesh Plot – produces a 3D view of spatial pixel-level information.
Arbitrary Charts – allows user control to guide the detection of black-circle registration marks.

Logging Levels – offer the ability to control the display and logging of different levels of messages from Imatest software: error, warning, info, and debug.
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.

July 21, 2014

Features

eSFR ISO automatically analyzes new ISO 12233:2014 Edge SFR chart (from the specification published Feb. 2014) using an interface similar to SFRplus. It can be run interactively in Rescharts or in fixed (batch-capable) mode (eSFR ISO Auto).

A Pass/Fail Monitor that can stay open during Imatest module runs provides immediate real-time Pass/Fail indication: valuable for testing Pass/Fail criteria for Imatest IT.

Support for Targa (TGA), ArriRaw (ARI), and DPX (digital cinema) files has been added. Not all DPX variants are supported: please send us files you have trouble reading.

Support for several video color spaces has been added: ACES, DCI-P3 (for projectors), Rec. 709 (Legal and Full), and Rec. 2020 (Legal and Full).

Automatic region detection is available for several test charts: Colorchecker, Imatest 36-Patch Dynamic Range, and Imatest Spilled Coins/TE265 Dead Leaves, as well as new versions of the Log F-Contrast, ISO 14524 and ISO 15739 charts that contain registration marks. Most settings can be made with the Options I ROIs… button in the Imatest main window.

Dynamic Range results have been added to the Multicharts/Multitest noise calculations. Density response can be displayed above the noise plot.

The Imatest main window has been redesigned to be larger with a more logical layout: buttons for Random/Dead Leaves, Log F-Contrast, Star, Wedge, and Any image sharpness have been added. A Last module button is displayed near the lower-left for convenience. The last module run by Multitest is displayed.

The Help mode button (bottom of Imatest main window) alters the window so that all buttons display their corresponding website instructions.

SFRplus shift-dependent geometry recalculation speeds up repeated SFRplus runs for real-time focus tests by not recalculating SFR region position unless there is a significant change in the position of the slanted edges.

Imatest IS push-interface is a C++ DLL version of Imatest IS with an extra interface layer that allows for simple communication with Imatest IS
