Removing Image Noise with Adaptive Filters

Dwayne Phillips
There is no such thing as a universal filter, but we can get close by building one that adapts to the local noise. Dwayne Phillips walks us through the math to make a filter look a little bit smart.

Effective Contour Creation with OpenGL Texture Mapping

Wenfei Wu
In graphics applications, "let the hardware do it" is generally good advice. Today's graphics hardware keeps getting better and better, and OpenGL knows how to exploit its capabilities. Even producing contour plots can be a fairly painless operation.

The Standard Librarian: What are Allocators Good For?

Matt Austern
Most of us use STL allocators without knowing it; Matt explains when we might want to invoke them explicitly or write our own, and how to go about it.

Effective C++ Standard Library: Explicit Function Template Argument Specification and the STL

Klaus Kreft and Angelika Langer
A subtle problem with templates that could bite you if you're not careful.

Generic<Programming>: Change the Way You Write Exception-Safe Code — Forever

Andrei Alexandrescu and Petru Marginean
Here's a handy template that makes exception safety a whole lot easier to achieve.

Conversations: Virtually Yours

Jim Hyslop and Herb Sutter
Guideline: virtual functions should be made private if possible. Surprised? This article gives the rationale.
