plugin

This plugin threshold an image using the Maximum Entropy algorithm, which aims at maximizing the inter-class entropy. Entropy is defined as -sum(p.*log2(p)), where p contains the histogram bin counts. This thresholding is very useful to segment images with few bright objects on large dark background. In ImageJ/FIJI you can acces this tool in Image->Adjust->Threshold and choose in the list In Aphelion, you can access this tool in Seglmentation->Threshold-> AphImgEntropyThreshold

quote:

This plugin allows to apply a free affine transformation to a 2D image in an interactive way.

The purpose of this plugin is to register—in other words, to align or to match—two images, one of them being called the source image and the other the target image.
