ImageJ 1.54g – Scientific image processing and analysis.

ImageJ is a public domain Java image-viewing and -processing program. It runs either as an online applet or as a downloadable application, on any computer with a Java 1.6 or later virtual machine, and can provide image analytics and basic editing functions.

Thanks to Yuekan Jiao, added a “16-bit histogram” option to the Image>Adjust>Threshold dialog and a ’16-bit’ option to the setAutoThreshold() macro function and the ImagePlus.setAutoThreshold(String) method. When this option is enabled, the full 16-bit histogram is used to calculate the threshold of 16-bit images (example).
Thanks to Eyal Rozenberg, the File>Import>Raw command uses the directory name as the image title when the “Open all files in folder” option is enabled.
Thanks to Zoltan Kis, the Process>Noise>Remove Outliers tools uses sliders for setting the radius and threshold.
Thanks to Nicolas De Francesco and Curtis Rueden, the macro language documentation (functions.html) is now included in ij.jar and is used by the Editor’s Macros>Function Finder command.
Thanks to Robert Baer, the “Associate ‘Show All’ ROIs with slices” option in the ROI Manager’s More>>Options dialog is now always enabled when ImageJ starts up.
Thanks to Christian Tischer, files with an “ome.tif” or “ome.tiff” extension are opened using Bio-Formats.
Thanks to Fred Damen and Michael Schmid, the ImageProcessor.getSliceNumber() method returns the stack position when not called from a PlugInFilter.
Thanks to Fred Damen, added the Dialog.getLocation(x,y) macro function.
Thanks to Philippe Carl, added the RoiManager.setPosition(c,z,t) macro function.
Thanks to Fred Damen, the second argument of the Dialog.addDirectory(label,defaultdir) function is no longer ignored when the user clicks on the “Browse” button.
Thanks to ‘Phiir42’, fixed bug with closed tables reopening after a macro finishes.
Thanks to ‘Ender’, fixed headless mode “Scale Bar” and “Show Info” bugs.
Thanks to Michael Schmid, fixed ImageCanvas.fitToWindow() bug with very small images or user resized windows (example).
Thanks to Michael Ellis and Michael Schmid, fixed a RotatedRectRoi rounding bug and a bug where newly created RotatedRectRois consisted of 5 points instead of 4.
Thanks to Volker Backer, fixed a Roi group bug with Fiji on Linux.
Thanks to Yuekan Jiao and Michael Schmid, fixed a rounding error with PointRoi.getContainedPoints().
Thanks to Guenter Pudmich, fixed a 1.54d regression that caused 16-bit grayscale PNGs to be opened incorrectly.
Thanks to Saleh Altahini, fixed bug with opening ImspectorPro MSR files.
