Info

Imatest Documentation Close figures closes all figures. You can close figures individually by the usual Windows methods — clicking the X in the upper right or right-clicking on the figure icon on the Taskbar and selecting Close. EXIF displays EXIF data for an image file. Most file formats supported when ExifTool is installed. Exif data can be saved in a text file in the same folder as the image for viewing/searching with the Save Exif data button. Exif viewer Open Fig file opens a Matlab Fig file saved during an Imatest module run. Unlike image files, Fig files can be manipulated— most importantly, 3D Fig files can be rotated for enhanced visualization. But Fig files should be used sparingly because they can be as large as several megabytes. Saved settings: Imatest saves a number of settings, including Font size, folders for opening and saving images, plot selection, and figures to save. To view or edit the settings, click the Settings menu (in the toolbar on the top of the Imatest window), then click View settings (ini file) or Edit/Reset modules. To restore these settings to their original defaults, click (in the toolbar on the top of the Imatest window), then click Reset defaults (all) in the Settings menu. The settings are stored in imatest.ini. Options I... and Options II... (bottom-right of the Imatest main window); also in the Settings dropdown menu) opens the boxes shown below, which allow several options to be specified. Options I 88 of 451
Imatest Documentation Options I for setting ROI options, Large file processing, and Batch run order. Expert vs. Basic mode affects the complexity of input dialog boxes. Basic (beginner) mode uses a simplified dialog box and uses defaults for settings that are not displayed. Modules are gradually being added. ROI (Region of Interest) section controls cropping options. SFR ROI filtering When Light filtering is checked the tests that validate the SFR ROI (region of interest) are relaxed. This can be useful when testing noisy images, rough edges, images of endoscopes or other devices with interfering patterns, but it can lead to errors if regions are selected carelessly. Normal filtering is the default. Stepchart ROI selection Automatic selection (the default) can be toggled. If it is turned off, a fixed number of patches (6-41) can be selected for Stepchart analysis. This option is useful when high noise in dark regions confuses the automatic ROI detection. Colorcheck, Distortion, Light Falloff Cropping options. You can select whether to ask for cropping and whether to use the last crop (for same-sized images). For Colorcheck you can also choose between traditional automatic patch detection and Multicharts-like patch detection, where all squares are shown in the fine adjustment window. LARGE FILES (Light Falloff, Distortion) These two modules typically use little or no cropping. As a result, memory may sometimes overflow. This setting offers the option of cutting the image dimensions in half (1/4x in area and memory) to avoid memory problems. Batch run order The actual order of batch runs may differ from the order of selection in curious ways that depend on the operating system or other factors. With one of the choices in this popup menu the run and selection orders should be the same. Reset restores defaults: it sets SFR ROI filtering to Normal, Stepchart ROI selection to Automatic, turns off all global folder settings, and checks Get EXIF data . Options II 89 of 451
