Algebraic Lens Distortion Model Estimation by Luis Alvarez, Luis Gomez and J. Rafael Sendra
With an algebraic approach to the estimation of the lens distortion parameters based on the rectification of lines in the image, we obtain the lens distortion parameters by minimizing a 4 total-degree polynomial in several variables.

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 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 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 by Nicolas Limare
Development prototype for the interactive selection of a sub-image, based on HTML-only tools with JavaScript enhancements.

Contrast Workshop by Nicolas Limare, Jean-Michel Morel, Ana Belén Petro, Catalina Sbert
Variations around Retinex and contrast correction.

Non-local Means Denoising by Antoni Buades, Bartomeu Coll, Jean-Michel Morel
non-local means denoising

Simplest Color Balance 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 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 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.

Image Curvature Microscope by Adina Ciomaga, Lionel Moisan, Pascal Monasse, Jean-Michel Morel
The sub-pixel algorithm computes the image curvature directly on smoothed level lines, and yields a microscopic visualization of the curvature map.

LSD: a Line Segment Detector by Rafael Grompone von Gioi, Jérémie Jakubowicz, Jean-Michel Morel, Gregory Randall
LSD is a linear-time Line Segment Detector that gives accurate results, a controlled number of false detections, and requires no parameter tuning. The method is based in Burns, Hanson, and Riseman method, and uses an _a contrario_ validation approach according to Desolneux, Moisan, and Morel theory.

ASIFT: A New Framework for Fully Affine Invariant Comparison by Guoshen Yu and Jean-Michel Morel

Retinex Poisson Equation : a Model for Color Perception by Nicolas Limare, Jean-Michel Morel, Ana Belén Petro, Catalina Sbert
An exact and fast implementation of the Land-McCann Retinex theory (1964) is achieved by means of a screened Poisson equation using only two DFTs.
