I have been very busy since the last few weeks… so the chroma key filter was put aside for a long time until today 
I have used conditional compile in the filter to avoid having if-else in the runtime, hopefully can increase performance… Anyone volunteer to measure it and post the different?

Make sure if you want to use this filter in Flash to install a new version ( 1.5 ) of PixelBender.
I tried to export it for Flash with version 1.0.352475 ( included with CS4 ) and the filter gave a strange output ( not in the pixel bender environment itself ).
With version 1.5 the filter works correctly in Flash as well.
