Imatest Master Changelog

What's new in Imatest Master 24.1.0

Apr 25, 2024
  • New Features:
  • 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.
  • 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.
  • Edge Information Metrics SNRi and Edge SNRi (Independent Observer Signal-to-Noise Ratios). Measures of the detectability of objects and edges.
  • Edge Information Metrics Matched filter design Procedure for designing electronic filters that optimize object and edge detection metrics, SNRi and Edge SNRi.

New in Imatest Master 22.2 (Oct 11, 2022)

  • 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.

  • 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. 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.

New in Imatest Master 3.10 (Aug 27, 2014)

  • The new Multitest module (known briefly as ColorTest) can analyze all the color and grayscale test charts supported by Multicharts in a fixed (i.e., non-interactive) module that can analyze chart image files in batches. It also includes most Stepchart and Colorcheck function.
  • Five new fixed modules that can also operate in batch mode have been created from Rescharts modules: Random/Dead Leaves, Star chart, Log F-Contrast, Wedge, and Any Image Sharpness. These modules can be accessed by clicking the Modules dropdown menu in the Imatest main window. These modules could be made into Imatest IT modules on customer request.
  • SFR and SFRplus run nearly twice as fast as version 3.9.
  • The Imatest IS (Image Sensor) edition has been upgraded in many ways. Auto reloads with the Edge/MTF plot are faster and more robust: they should be nearly unbreakable when the image is interfered with.
  • You can control Imatest with files other than the default imatest.ini by clicking Select INI file (in the INI File Settings dropdown or the Manage Settings window. This can be particularly valuable for testing control files for Imatest IT.
  • The new Chart Quality Index (CQI) measurement indicates how large a chart needs to be in order to provide accurate MTF measurements with a given camera.
  • Settings windows have been enhanced for most analysis modules with clearer, more consistent layout and colors. Expert/simplified modes can be selected in SFR, SFRplus, Stepchart, and Colorcheck.
  • The SFR: Current File button has been removed from the Imatest main window. Rescharts Slanted-edge SFR is a better way of modifying the image analysis.
  • The Image Stabilization module has been added for measuring effectiveness of image stabilization and comparing SFRplus results of different imaging systems.
  • Log F-Contrast displays the chart modulation and contrast ratio more clearly.
  • SFRplus settings can be updated by clicking Settings, SFRplus Auto settings in the Imatest main window without having to read an image file into Rescharts SFRplus Setup.
  • Generalized Read Raw includes a pixel offset (integer to subtract from input data).
  • Multicharts has new HS (Hue, Saturation from HSV and HSL color models) displays.
  • Random/Dead Leaves provides stronger support for Dead Leaves-type texture charts, particularly for the new Imatest “Spilled Coins” chart, which is more uniform and has better scale-invariance. More information in these pages: Texture Examples | Dead Leaves Measurement issue
  • SFRplus distortion and field of view calculations have been made more accurate and robust: the best of the 3rd order, 5th order, and arctan/tan calculations can be selected. A radial distortion plot has been added.
  • A new Functional Interface is available for test lab environments that need simple operation and consistent settings.

New in Imatest Master 3.9 (Aug 27, 2014)

  • Imatest main window: Explore image file folder and Explore recent save folder have been added to the File dropdown. INI File Settings have been given their own dropdown to minimize clutter. Explore INI file folder has been added. The INI file Editor (useful for fixing errors and for setting up INI files for the Functional Interface and IT) has been greatly enhanced.
  • Most modules: Dialog boxes for selecting new regions and repeating regions for same-size images have been greatly improved, with clearer instructions and options for lightening and (where appropriate) zooming the image. The last image file name is saved and displayed in the File select dialog box (a time-saver for repeated runs). Region settings for several image sizes are now saved for most modules (except for SFR and SFRplus). JSON output has been added (in addition to XML and CSV).
  • Raw file support has been greatly strengthened (dialog boxes are somewhat changed).
  • Multicharts supports the following charts: general mxn grid, SMPTE/Hale color bars, Image Engineering TE226, DSClabs DreamCatcher 48, and Image Science Associates ColorGauge. Multicharts noise analysis has been extended to include several types of chroma noise as well as image sensor noise (from raw files). The Color correction matrix has improved linearization options (based on measured tonal response), and a file for weighting patches (for the matrix optimization) can be entered. The 3D Color difference display now includes split colors, making it very convenient to correlate ΔC and ΔE measurements with perceived color differences.
  • Multicharts and Stepchart support the Imatest 36-patch Dynamic Range chart, which is available in the Imatest Store.
  • Blemish Detect detects light (and both dark and light) blemishes in addition to the standard dark blemishes. It can perform nearly all functions of Uniformity. Third order exponential filtering (exp(-x3)) can be selected. Contiguous blemishes are counted (not just total blemish pixels) and can be displayed in the Blemish count plot. Additional display options show blemish regions more clearly.
  • SFRplus can run without the top and bottom distortion bars (select Auto- no bars in the Rows box). The Field of View calculation has been improved (particularly for distorted images). Rejection of interfering patterns outside the chart has been greatly improved. Additional region selection options include the Skype specification (3 regions) and custom regions specified by an Edge ID file.
  • SFR and SFRplus: Several rise distances in addition to 10-90% (e.g., 20-80%) can be calculated. The Image or Image & Geometry display has a crop to ROI feature the displays an enlarged region with edge and MTF plots below, providing an excellent visual correlation between appearance and measurements.
  • Log F-Contrast: The MTF/contrast 2D contour plot is more strongly smoothed for improved readability and accuracy.
  • Uniformity (formerly Light Falloff): Extra smoothing option greatly improves contour plots. Hot and dead pixel thresholds can be specified by percentage above or below neighboring pixels (in addition to absolute levels). An Optical Center calculation has been added.
  • Test Charts: The 12-patch ISO-14524 OECF chart, revised low-contrast (4:1) ISO-12233 edge chart, SVG checkerboard, and 36-patch Dynamic Range chart (for reference; not printing) have been added.
  • New web pages: Skype video specification support | Validating the Imatest slanted-edge calculation
  • IT/DLL (Industrial Testing – non-GUI version) can now receive images (raw or processed) directly from the calling program and pass detailed results back to the calling program via easy-to-parse JSON objects. Pass/Fail criteria can be entered (most useful for production testing, but available in GUI versions). Detailed IT Online documentation, including INI file references, is available.

New in Imatest Master 3.8 (Aug 27, 2014)

  • I3A CPIQ (Camera Phone Image Quality) enhancements: The Dot Pattern module has been added for analyzing distortion and lateral chromatic aberration (LCA). The Dot pattern and ISO-15739 charts have been added to Test Charts. The CPIQ Acutance measurement (similar to SQF) has been added to SFR and SFRplus. The CPIQ color uniformity metric (ΔCmax) has been added to Light Falloff and Uniformity Interactive.
  • Noise analysis has been added to Multicharts. Support for extremely distorted SFRplus charts has been improved.

New in Imatest Master 3.7 (Aug 27, 2014)

  • An analysis of Random (Spatial-invariant) patterns has been added to Rescharts. Since these patterns are unaffected by software sharpening but strongly affected by noise reduction, they reveal how well fine texture is rendered.
  • A temporal noise analysis (which requires reading two input files) has been added to Colorcheck and Stepchart.
  • A powerful noise reduction technique for slanted-edge MTF calculations has been added to SFR and SFRplus.
  • After a Color correction matrix has been calculated in Multicharts the corrected image used for the calculation can be saved. Images can be read in, color-corrected with the matrix, and saved.SFRplus region selection is much more tolerant of large amounts of barrel distortion.
  • An Edge Roughness plot that distinguishes noise from aliasing has been added to SFR and SFRplus.
  • Universal Test Target (UTT) color and grayscale (stepchart) patterns are now supported by Multicharts and Stepchart
  • MTF patch levels are displayed on the SFRplus Tonal response plot.
  • The Edge & MTF plot in SFR and SFRplus can now display unnormalized edges, which are useful for diagnosing situations where a channel can saturate.
  • Secondary readout has been added to several Rescharts modules: Star Chart, Wedge, Log Frequency, and Random.
  • Imatest can be run with saved settings using Custom Icons or shortcuts.

New in Imatest Master 3.6 (Aug 27, 2014)

  • Several modules have been added:
  • Find Sharp Files allows batches of files to be ranked for sharpness.Blemish Detect detects visible sensor defects, using a filter based on the Human Visual System. It is highly tunable to match viewing conditions for individual applications.
  • Uniformity-Interactive performs all Light Falloff (vignetting and sensor nonuniformity) measurements in an interactive window, compatible with the Imatest Image Sensor edition.
  • Wedge (part of Rescharts) analyzes hyperbolic and trapezoidal wedges (part of the ISO 12233 and other charts) for the onset of aliasing (“vanishing resolution” in CIPA DC-003) and MTF.Generalized raw read capability enables noncommercial raw files (not supported by dcraw) to be read. A new Lens-style MTF plot is similar to MTF displays in the Canon, Nikon, and Zeiss websites. Batchview can display lines as well as bars. Data Cursor (now available in all Figures and most interactive modules— Rescharts, Multicharts, etc.) displays numeric values of plots and image pixels. Multiple 3D plots can be produced by SFRplus (running in auto mode). Test Charts can create a USAF 1951 resolution chart. Diffraction-limited MTF is displayed in SFR and SFRplus MTF plots when the pixel spacing is entered. Angular frequency (cycles/milliradian and cycles/degree) is available for MTF measurements.A new web page shows the relationship between MTF Curves and Image Appearance.

New in Imatest Master 3.5.1 (Aug 27, 2014)

  • Additional geometric information has been added to the Image & Geometry display in SFRplus. Numerous small improvements have been made to the interface: User interface locations are much more tightly controlled. XML data for SFR and SFRplus has been restructured in preparation for an upcoming Database product.

New in Imatest Master 3.5 (Aug 27, 2014)

  • Sensitivity (ISO speed) measurements have been added to Stepchart, Colorcheck, SFRplus, and Multicharts. The dcraw interface has been updated to include gamma selection and an option to turn off auto white level (import for sensitivity). A new region selection in SFRplus allows detailed 3D plots to be generated from charts with two contrast levels (selecting all important high contrast edges). SFRplus CSV output has been enhanced. Corrected a bug in SFRplus batch (multi-file) runs

New in Imatest Master 3.4.1 (Aug 27, 2014)

  • SFR and SFRplus calculations have been sped up significantly. A Speedup checkbox in both modules provides additional speed by removing some calculations (SQF, noise statistics, clipping check, etc.) A Top/Default view toggle button has been added for SFRplus 3D plots. Color correction matrix calculations have been enhanced. A Speedup button Light Falloff skips calculations when the corresponding plot is not called.
