Mind Mapping Tool: Freeplane

Freeplane is a fork of the FreeMind project (open source mind mapping software). Freeplane fully supports the FreeMind file formats. The german Wikipedia site says that Freeplane is the only active fork of FreeMind. Therefore I started using Freeplane.

Gantter - A web-based project planning tool

Today I have read an article in the german computer magazine c't. In this article they propose a new web-based project planning tool named Gantter.
I haven't tested it yet, but I will.

MATLAB and pseudo color images

This post is about how to generate a pseudo color image from a grey scale image.
1.) You have to read the grey scale image (e.g. a bitmap or jpeg) with the function imgIn = imread('ImageName.bmp').
2.) Then convert the image to double with imgD = im2double(img).
3.) Call the function hPCImg = pcolor(imgD).
4.) Remove the Edges with set(hPCImg, 'EdgeColor', 'none')
5.) Set the colormap, e.g. colormap( jet(8) )) for a view with 8 different color.

Face detection and face recognition in 2D and 3D

At the moment I'm looking for libraries, that support face detection and face recognition implemented in C++, C or Java.
Beside that, I'm looking for information about the algorithms.

Writing plugins in C++ - pugg (open source c++ plug-in framework)

I am looking for people that have experience in using, or interessted in using, the plugin framework pugg, available at:
http://pugg.sourceforge.net/

What is your opinion on the framework pugg?
Please feel free to leave a comment.

Edit 2010-02-25:
I decided not to use the framework pugg.
In my opinion the framework is inconsistent, because one plugin can support more than one functionality.
I need a plugin framework, that only allows plugins with one "run()"-method.

Plugins in C++

I am looking forward to write a software that defines a plugin interface.
The main functionality will be defined by each interface definition.

Afterwards I would like to configurate the software by XML files. Then by the entries of the XML file, a specified plugin will be used to process the data.

By this way it is possible to create a modular system.
I would like to define different filter interface (I call the plugins filter, because data will be processed) for the different tasks that will be needed.
