Announcement: Parallel Spectral Deconvolution Plugin

[Piotr Wendykier]

Hello,

A new plugin, called "Parallel Spectral Deconvolution", is available at:

http://piotr.wendykier.googlepages.com/deconvolution

Features:

- 2D and 3D Generalized Tikhonov, Tikhonov and TSVD image deblurring.
- Multithreading.
- Reflexive and periodic boundary conditions.
- Automatic choice of regularization parameter (based on GCV).
- Very fast update option.
- Non-modal GUI.
- Can deblur 4096x4096 image in less than 7 seconds (on quad-core).

This plugin uses JTransforms - first open source, multithreaded FFT library
written in pure Java - available at:

http://piotr.wendykier.googlepages.com/jtransforms

I hope that you will find it useful.

Hi!
I get the following error list when I try the plugin:

java.lang.UnsupportedClassVersionError: Bad version number in .class file
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClass(Unknown Source)
    at java.lang.ClassLoader.defineClass(Unknown Source)
    at ij.io.PluginClassLoader.loadClass(PluginClassLoader.java:246)

    at ij.Executer.runCommand(Executer.java:95)
    at ij.Executer.run(Executer.java:49)
    at java.lang.Thread.run(Unknown Source)

I have the latest, ImageJ, the latest Java and winxp. Any ideas?
Thank you!
Przemko

Przemko,

First of all, I have updated binaries on my website, so please
download and install the plugin again.
If this doesn't help, then make sure what version of Java is used by ImageJ:
Plugins -> Utilities -> ImageJ Properties...
It has to be at least Java 1.5

Still doesn't work for me with new binaries and Java 1.5.  Dave
