This is a relatively simple chroma key plugin for removing the green background from an image. It's based on the algorithm presented in the paper here: http://www.makebelie...s/SAICSIT99.pdf with an addition to reduce the green hue at the edge of objects. It's a terribly simple routine compaired to many and certainly could stand improvement, but seems to do the job as well as many of the $100 programs I've tried.

cool plugin,

Updated the plugin to handle both green and blue chroma keys. Also optimized some of the code.

Any chance of some pictures to demo it please? :wink:

[tarheit]

I just used the demo pictures that were in the demo version of GreenscreenWizard (http://store02.prostores.com/servlet/tu ... een/Detail
I just purchased a piece of green cloth so I haven't had a chance to take any of my own yet.

Looks good. Thanks.

This might be more useful as some sort of video editing tool. Which, I wish I could find free.
As far as photo editing for experienced users, I don't really see this being a commonly used tool (over pdn). There's already plenty of alternative, more effective ways of doing what this does. I don't need the background to be a certain, solid color to produce the same thing in the example pictures I've seen.
That's just my personal opinion though. I'm sure other people probably need this. Like perhaps, scrubs at tourist attractions taking your picture in front of a green screen. But, I'm sure they already have purchased professional equipment.

You use this plugin from within Paint.NET. There is no need to code anything.

I have a file with a lot of yellow and it deletes that too. I've tried using the adjustments but can't seem to get it right. Any ideas? Thanks.

While the program does a good job of keying out the green, I find that unless your format and size between the layer are the same this is something of a pain. Perhaps I'm simply not familiar enough with the program to understand. I can't simply drag the size so my subject on the green screen fits properly into prespective on the background scene. It also seems very difficult to position it. What am I doing wrong? I cannot seem to figure out how to do simple manipulatio of the size and placement of the different layers. If I simply use the drop down to change the size, both pictures change instead of the one.



Otherwise the effect of keying out the green works very good.
