Move slcon 2016 to its own file

In the interest of linking consistency we should maybe immediately
create a 2017.md for the next conference.

Let us define "text" as the semantic data + structure that results from parsing strings. Imagine that a software system has + a "text engine" at its kernel.

An application retrieves a configuration parameter by + querying the text engine. In such a system parsers for particular formats or + languages would not be embedded into particular applications or commands, + they would be stand-alone software units with the sole purpose of converting + a string into a semantic representation in the text engine's repository. + Applications would not have to deal with and not be tied to particular file + formats and languages, and the user would be able to choose the format or + language to use for any configuration statement.

Since arrays of numbers are + natively represented in C, this language is well-suited for image + processing algorithms. Moreover, many complex image processing + algorithms are pipelines of simple, independent steps. Thus, + the UNIX programming environment is an ideal platform for image + processing, where several simple programs written in C share + information through UNIX pipes. In this talk, we will see many + examples of simple image processing utilities (blur, local maxima + detection, interpolation, warping, pointwise algebraic expressions, + morphological filters, block matching, optical flow, image fusion) + and how they are naturally combined to perform advanced imaging + techniques; in the selected example, we show a reflection removal + method based on the combination of several images.
