Finite Difference Schemes for MCM and AMSS
by Marco Mondelli, Adina Ciomaga
The two algorithms apply finite difference schemes respectively for Mean Curvature Motion and Affine Morphological Scale Space.
A Real Time Morphological Snakes Algorithm
demo
by Luis Alvarez, Luis Baumela, Pablo Márquez-Neila, Pedro Henríquez
We use a morphological approach to Partial Differential Equation discretization to design a real time algorithm for snake evolution
Self-Similarity Driven Demosaicking
demo archive
by Antoni Buades, Bartomeu Coll, Jean-Michel Morel, Catalina Sbert
The SSD demosaicking algorithm interpolates missing color values of a CFA mosaick by using the self similarity of the image.
Image Crop
demo
by Nicolas Limare
Development prototype for the interactive selection of a sub-image, based on HTML-only tools with JavaScript enhancements.
Contrast Workshop
demo
by Nicolas Limare, Jean-Michel Morel, Ana Belén Petro, Catalina Sbert
Variations around Retinex and contrast correction.
Non-local Means Denoising

Simplest Color Balance
demo archive
by Nicolas Limare, Jean-Michel Morel, Ana Belén Petro, Catalina Sbert
This color balance improves an image by stretching each color channel to [0,255] by an affine transformation with the saturation of a user-defined percentage of pixels.
Cartoon+Texture Image Decomposition
demo archive
by Antoni Buades, Triet Le, Jean-Michel Morel, Luminita Vese
The cartoon+texture algorithm decomposes any image into the sum of a cartoon part, where only the image contrasted shapes appear, and a textural part with the oscillating patterns.
Micro-Texture Synthesis by Phase Randomization
demo archive
by Bruno Galerne, Yann Gousseau, Jean-Michel Morel
micro-texture synthesis using Fourier phase randomization
Image burst denoising
by Toni Buades, Yifei Lou, Jean-Michel Morel, Zhongwei Tang
A clear image can be obtained from a sequence of noisy images by registration, video equalization, noise estimation and denoising.
