Hello, We are using ordinary CCTV cameras to grab color pictures. The representation of the picture in our image processing application is in RGB format. Is it possible to determine wavelength of the light at particular pixel from RGB values ? The purpose is to cut out all the white light and keep only infrared spectrum (above 850nm). We need software solution, because hardware solution (like IR pass filters on lenses) is not acceptable for us. Thanks for your advices.
