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.

This plugin allows to analyze the local direction and frequency of sinusoidal waves, for example muscle repetitive stripy pattern.

The output are optionally smoothed lambda (inversely proportional to the frequency) and phi (direction in degrees).
