Author: Bombace Fabio ( fabio.bombace at gmail.com)
Advisor: Prof. Sebastiano Battiato (battiato@dmi.unict.it)
History: This plugin was implemented in August 2013 - Computer Forensics

Works with:

JPEG, tiff, and other type of images.
ImageJ's version: 1.47v (used to develop this plugin)
Source: ComparePlugin.zip
Installation:

Download ComparePlugin.zip and unzip its content in the plugins folder, then compile "Compare_Plugin.java" with the "Compile and Run" command. Restart ImageJ to add the "Compare Plugin" command to the Plugins menu.

Description:

This plugin implements a function of visual compare of original and modified image in ImageJ, like the "compare" function in Amped5 software.

This plugin allows you to make any change to the active image, and until you don't save it with the "save" command listed under the menu item "File" in imageJ, you can display a new window containing, on the left the original non-modified image, while on the right the modified image, for a visual compare.

The new window created, containing both the original and the modified image, can be modified too as a normal image. N.B. : the images in the new window are pasted/created without loss of quality.

Usage: Open an image that you want to do some operations/modifications, and do it; When you want to compare the original image with the modified image, click on the "Compare Plugin" voice under the menu item "Plugins" in imageJ.

Now, you can continue working on the new window that is appeared, or discard the compare closing the new window.
Bugs:

If you want to compare only the selected or cutted part of image, you MUST create a new image with the desired part of image and save it on your local/network storage.

N.B. : workout for this bug; You can simply copy the region that you are interested, click on the "File->New->Image..." command in the imageJ, paste it on the new window created, and SAVE it.
