Image Processing Online Demo

These demonstrations run on any moderm browser supporting HTML5.

Mathematica CDF Player

Requires the CDF Player of Wolfram Mathematica.

Exploration of the B-Spline

Robin Lang and Daniel Schmitter, 2017

This demo is very soon available.

Apple iOS Apps

These Apple apps are available on the Apple store and run on iPhone.

iMondrian Sparse Stochastic Processes

Ricard Delgado, 2011

This app generates artistic representations of Mondrian processes. These processes are named after Piet Mondrian (1872-1944), a great figure in the neoplasticism style known for his grid-based paintings.


Filter Creator

Michael Rusterholz, 2012

Filter Creator helps you to better understand the mathematics of discrete and continuous audio filters and is particularly aimed at students of signal processing classes.

Image Processing Java Applet

These Java applets are running on browsers supporting a recent Java Virtual Machine.

Research Demos

Florian Luisier

A new approach to color or grayscale image denoising.
Variational Levelset Spline

Olivier Bernard

New formulation of level-set modeling the implicit as a continuous parametric function expressed on a B-spline basis.
