VirtualDub is a very common freeware program for video capture and for analysing AVI video streams, see http://www.virtualdub.org/.

VirtualDub allows transcoding of video with filters inserted in the path between source and destination. It contains some build in filters and furthermore offers an open interface to plug in external filters.

Various filters are hosted or referred at http://neuron2.net/.

Easy Histogram Equalization

This filter is an easy adjustable histogram equalization filter that requires only one parameter for configuration.

The Algorithm is described in this chapter (in german) of my image processing lecture.

The filter is not optimized for speed.
