Adaptive Threshold Edge Detect

An alternative edge detector based on the implementation in the OpenIllusionist project.

The original algorithm requires scaling down of the entire image area to be processed and it would have to be completely re-written to work with GIMP tiles. Since this plugin is a simple adaptation of the original algorithm it does not make use of tiles and therefore it needs to allocate a lot of memory to work. So please be aware that it may have problems if you attempt to use it on an extremely large image!

The algorithm is based on research at the University of York and was developed primarily for use with fiducial detection in live video. It was designed to improve detection of connected edges and reduce the effects of ringing edges that often occur in video streams and compressed still images.

The source and Linux binaries can be downloaded from my github plugins repository.

A more detailed description along with some example images can be found on my blog.
