Chroma Key (green screen) Edges

[greenware]

I'm removing the green from an image and overlaying it on a background and everything is working great -- except for the edges - especially around the hair. I've seen some other green screen software apply some "fuzzy/Blurring" to the edges to blend it better. Is there some method that this control can do similar?

Here's what I'm doing now:

Code: Select all

        Dim Imaging1 As New GdPicture.GdPictureImaging
        Dim Left As Integer
        Dim Top As Integer
        Dim Width As Integer
        Dim Height As Integer
        Dim MainImage As Integer = Imaging1.CreateGdPictureImageFromFile(gdGreenFGRND.Tag)
        Stat = Imaging1.fxRemoveBackgroundChromaKey(MainImage, ColorKey.ColorKeyGreen, HSThreshold.Value, HSMinVal.Value)
        
        gdGreenFGRND.GetDisplayedArea(Left, Top, Width, Height)
        Dim newimage As Integer = Imaging1.CreateGdPictureImageFromFile(gdGreenBKG.Tag)
        Imaging1.Crop(MainImage, Left, Top, Width, Height)
        Imaging1.ResizeHeightRatio(MainImage, 2100, Drawing2D.InterpolationMode.HighQualityBicubic)

        Imaging1.DrawGdPictureImage(MainImage, newimage, 0, 0, 1500, 2100, Drawing2D.InterpolationMode.HighQualityBicubic)
        Imaging1.ReleaseGdPictureImage(MainImage)
        Imaging1.SaveAsJPEG(newimage, sPath & "\GreenScreen.jpg")
        Imaging1.ReleaseGdPictureImage(newimage)

Thanks.
John

Hi John,
Could you please show me an image to I can understand exactly what you are talking about and better help you.

Attached image shows what I'm talking about.

I'm guessing they have some algorithm that detects the edges around the "green" and does some sort of anti-alias before removing the green color.

Thanks.

I received an email from Sami that you will be able to add something to do this in the future.

Is there any way I can be notified when you begin working on this and when it is completed? This issue has turned into a real stumbling block for my client.

thanks.

Hi John,

Unfortunately, we do not have such a feature. We will add something like this in the future, but there is no timeline for that yet.
