I have to develop a Flash app that would remove green screen part of the photo and will replace it with desired background. Flash app is an SWF file where i load my photos (taken against a green screen). What functions/filters can be used to achieve that - i have to add the green pixels removal has to be automatic when the photo is loaded to the app. I heard something about the colorMatrix filter or something like this, but I would like to hear an expert opinion on that.
Attached a sample of what I am trying to achieve.
