Imaging

This plugin can be used to add synthetic Poisson-distributed noise to an image in order to simulate shot noise of various signal-to-noise ratios. It can be used to generate benchmark images in order to assess the accuracy and robustness of image processing algorithms as a function of the noise level present in images.

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).
