Imagine that you have captured beautiful fluorescence frames from GFP-fusioned protein with a color camera. In addition to bright green stained cells, you also observe that most cells have an orange-yellowish staining because of a treatment with a protein kinase inhibitor that shows some fluorescence. In order to remove the orange background staining, I understand that the best approach is to use a narrow-band emission filter in the cube. This is something that we definitely will try once we get such filter. In the meantime, we have these beautiful time-lapsed images that we would like to enhance. If the background color were red instead of orange, we all would consider appropriate to separate RGB channels and then pick the green one. However, RGB channel separation does not render proper background removal in this case. So my question: Is there any way (or plugin) of post-processing such images to remove the orange background while maintaining the green signal? Thanks,
