Dear all,

We need to minimize the maintenance risk and effort and our demo system. 
I try to contribute to it by enforcing standard demo settings.

As a rule of thumb, when you design a new demo, the first question is: 
is the demo type similar or identical to an already existing standard 

In this case which is frequent, I propose to leave no other choice to 
the redactor than a copy-paste of the former ones with the minimal 

Or, if the redactor thinks that a new setting is widely preferable, then 
this change should be accepted by all and applied by the redactor to all 
equivalent demos, not just the one he is in charge of.

This exigence comes up naturally for scientific reasons. All equivalent 
algorithms must be tested by users in exactly the same way.

We are preparing groups of demos,  "benchmarks", which must therefore 
have EXACTLY the same settings. Their demo sites should look identical 
to the users.

I enclose the current list of projected benchmarks below. Each one is 
expanding rapidly. I invite you eagerly to fix a unique format for each 
benchmark. If several editors take care of one benchmark, they should 
arrive at a final proposition.

We are currently preparing seven such benchmarks. I enclose their list 
of demos and the current redactors

A) Denoising : José Luis, Miguel, Pascal Getreuer
+ BM3D
+ NL-means PCA

B) Demosaicking: Pascal Getreuer


C) Example based texture synthesis Nicolas, ???
+ Heeger Bergen
+ Wei Levoy
+ Portilla Simoncelli

D) Image interpolation  Pascal Getreuer

E) Epipolar rectification Pascal Monasse, Gabriele
+ 3 more

F) Various color-contrast adjustment  José Luis
color balance
+ histogram piecewise linear
+ gamma correction

G) Stéréo  Pascal Monasse, Gabriele
+ several block matching
+ several masks

H) Segmentation

I) gestalt detection
