ImageJ Plugins / News: Recent posts

1) Recompiled code to be binary compatible with Java 1.2 and newer (previously only 1.5 and newer), intended to resolve bug report #1470386.

2) Updated dcraw executable binaries to v.8.13.

The DCRaw Reader plugin opens raw image from over 200 digital cameras (Canon EOS 20D, Nikon D50, …). The binaries and source code the plugin are available at:

http://ij-plugins.sourceforge.net/plugins/dcraw/

Note that reading of 48 bit RGB images requires ImageJ v.1.35p or newer.

The DCRaw Reader plugin decodes images using DCRAW program created by Dave Coffin. The source code for DCRAW and the full list of supported cameras can be found at: http://www.cybercom.net/~dcoffin/dcraw/... read more

This is a bug fix release.

• Fix bug 1066969: First slice replaces all slices in 'Compressed' TIFF files.

Fixed the problem by explicitly duplicating each slice in net.sf.ij.jaiio.BufferedImageCreator.create(ImagePlus src, int sliceNb). The problem was caused by unexpected side effect of ij.ImagePlus.setSlice(int).

New plugin for texture synthesis using image quilting is available at:
http://ij-plugins.sf.net/plugins/texturesynthesis/.

The Image Quilter plugin performs texture synthesis using image quilting algorithms of Efros and Freeman: http://www.cs.berkeley.edu/~efros/research/quilting.html. The code of this plugin was originally developed by by Nick Vavra. Original code and description is available at: http://www.cs.wisc.edu/~vavra/cs766/. ... read more

Bug fix:

• Preserve 256 colors in 8 bit COLOR_256 images, even if they color map reports less colors.

http://ij-plugins.sourceforge.net/plugins/imageio

Bug fixes:

• Fixed problems saving 8 bit gray level images in cases when ImageJ had 16 bit color map for them.
• Fixed problem with use of 'save as' plugins in macros.

Developer visible changes:

• Added subdirectory example with with simple illustration how IJ-ImageIO can be used as a library.
• Minor changes to source based on feedback from 'FindBugs'
• Updated Javadoc documentation.
• ImageJ updated to v.1.33m.

ij-color v.1.0 contains plugins for color space conversion and processing of color/multiband images:

> RGB to CIE Lab stack - Converts image pixels from RGB color space to CIE
Lab color space.

> CIE Lab stack to RGB - Converts image pixels from CIE Lab color space
to RGB color space.

> Multiband Sobel edges - Sobel edge detector that supports multiband and
color images.... read more

New set of plugins for segmentation of images through thresholding and pixel-based clustering. A pixel based clustering is a generalization of thresholding that can be used for both gray level and multi-band images (for instance, color images). Plugin install in ImageJ under: Plugins/Segmentation. Brief online help installs under: Help/About Plugins.

Bug fix: Written files were always deleted (only partial writes due to error should be deleted)

Bug fix: Error message was shown when save dialog was canceled.

<b>Changes from version 1.1.0</b>

• Use new IJ feature allowing to distribute plugins in JARS

• Save dialog now maintains file name when file type is changed

• New option dialog to select TIFF compression options

• "JAI Reader" plugin renamed to "Plugins/Image IO/Open ..."

• "JAI Reader with preview" plugin renamed to "Plugins/Image IO/Open with preview..."... read more

ImageJ packaged for easy installation on Sharp Zaurus PDAs was updated to most recent version of ImageJ 1.30q. Thanks to Wayne Rasband who made it possible. The package is named imagej_1.30q-1_arm.ipk. Screenshot and download available at http://ij-plugins.sourceforge.net/imagej-zaurus

ImageJ packaged for easy installation on Sharp Zaurus PDAs is available. It is based on ImageJ 1.27z (later versions have some problems running on Personal Java). The package is named imagej_1.27z-1_arm.ipk. Screenshot and download available at http://ij-plugins.sourceforge.net/imagej-zaurus

Version 0.3 of ij-3Dplugins brings primarily new set of plugins, VTK Filters, plus some bug fix and enhancements to existing plugins.

New & improved:

• Set of plugins for direct access to native VTK 3D filters: anisotropic diffusion, Laplacian, median, erosion, dilation.

• Connected threshold growing - improved GUI, support for 16 bit images

• 3D Toolkit plugins - better error detection

• Number of related API extensions... read more

IJ-JAI-ImageIO v.1.1.0 adds scripting support and assembling of multiple files into stacks.

1.0.4 is a bug fix release resolving problems related to saving 16 bit images and 'inch' as a calibration unit in TIFF images.

JAI Reader with Preview now offers option to open only selected pages (images) for files containing multiple pages (images).

Two simple plugins perform one-sided 3x3 median filtering:

MEDIAN LIGHT: Performs median filtering only on light pixels, that is, a pixel is modified only if its intensity is more then a median intensity value in its neighborhood.

MEDIAN DARK: Performs median filtering only on dark pixels, that is, a pixel is modified only if its intensity is less then a median intensity value in its neighborhood.

Version 1.0 resolves all outstanding issues and known bugs. Main feature added since beta is support for Image/J's TIFF description strings.

JAI Image I/O bundle is a set of plugins for Image/J to read and write images using Java Advanced Imaging (JAI) 1.1.1 codecs (included in the bundle).

Most important functionality that this bundle adds to what already available in Image/J and its plugins is ability to read 16 bit, 32 bit, and float images from TIFF images that use tiles or compression. Image/J built-in TIFF reader does not support tiles and compression. JIMI plugins correctly read only 8 bit images.... read more

JAI Image I/O bundle is a set of plugins for Image/J to read and write images using Java Advanced Imaging (JAI) 1.1.1 codecs (included in the bundle). This a beta release (v.0.8) with basically all functionality intended present.
