Variational algorithms to remove stationary noise. Application to microscopy imaging. This plugin allows to denoise images degraded with stationary noise. Stationary noise can be seen as a generalization of the standard white noise. Typical applications of this plugin are:

- Standard white noise denoising using a total variation and fidelity term minimization. Even though total variation denoising is not the state of the art (regarding SNR improvement), it may be very valuable for further tasks such as image seg- mentation).

- Destriping (the problem that motivated us to develop these ideas). 

- Deconvolution (even though most users won't be able to use this feature).

- Cartoon + texture decomposition which might be useful to compress images, analyse textures or simplify segmentation like tasks.

A clear tutorial on how to write a MATLAB script to segment clustered cells.

The full script is downloadable near the bottom of the article. 

Matlab toolbox to analyze single molecule mRNA FISH data. Allows counting the number of mature and nascent transcripts in 3D images. See 2513. Following toolboxes are required: - Optimization toolbox - Statistics toolbox - Image processing toolbox - (Optional) Parallel processing toolbox

Input data type: 3D image

Output data type: CSV

A Jython script using the plugin : Register Virtual Stack Slices It takes a sequence of image slices stored in a folder, and delivers a list of registered image slices (with enlarged canvas). One of the images in the sequence can be selected by the user as reference and it will remain intact. The plugin can perform 6 types of image registration techniques: - Translation - Rigid (translation + rotation) - Similarity (translation + rotation + isotropic scaling) - Affine - Elastic (via bUnwarpJ with cubic B-splines) - Moving least squares All models are aided by automatically extracted SIFT features.

(from the webpage) >This usage example shows how to produce two-color images from spectrally unmixed data sets. It was written for an Alexa647/Alexa700 measurement on the Würzburg 1 biplane setup as documented in [Aufmkolk2012]. The first two tasks in this example produce prerequisite knowledge for the image generation, the alignment information (Produce linear alignment matrix) and the F2 ratios, i.e. the relative intensity of fluorophores between the channels.
