Given that you have to detect vegetation and soil in images your goal must be to make sure all vegetation and all soil are different looking in the resulting image or, that you can make them different enough to be detected. ICC profiles are not the best tool for this job. Essentially an ICC profile can be created from the camera's spectral sensitivities at ...

Your best bet is probably to use a color target with known colors, but lighting throughout the scene is going to cause lots of variation in the scene so unless your threshold for the difference is pretty high, you are likely to run in to problems regardless.

You use color references to create an ICC color profile for the specific lighting conditions and camera settings, then take shots and the color information contained in the pictures plus the ICC profile provides you with the proper color information. Check out some of the color targets through this link. I personally use the ColorChecker Passport. Make ...

My name is Jessica. I am an art student at the Art Institute of Pittsburgh Online Division. Printers use a color system of CMYK or Cyan, Magenta, Yellow, and Black, while monitors use an RGB color system or Red, Blue Green. If you want to make sure your pictures are exactly what is going to be printed, you should open up Photoshop, create a new document, ...

You have to make a distinction between mixing lights and mixing ink. When you take a picture, whatever camera you have (Digital, Analog, iPad, iPhone...) you are capturing lights. And according to physics laws, in the lights, the white is the mix of all other colors. The rainbow is a good example of lights diffraction. It's simply a separation of the white ...

Cameras are RGB because of the color filters over each of the pixels (photosites) on the sensor. There are a couple of rare cameras with a filter that instead samples cyan, magenta and yellow (not sure about luminance (black)), however this then would require a conversion to RGB to work with most screens and even a lot of photo printers which are RGB based. ...

Inherently, no. The RGB model is natural for recording light, and the CMYK model is natural for printing (where reflected light is subtracted). But see Are RGB numeric values equal to CMYK percentages? — the loss in conversation isn't inherently because RGB to CMYK is inherently lossy, but because the actual color spaces of the devices used are different, ...

So, the vast majority of sensors are RGB (the array is usually 1 red, 1 blue, and 2 greens or Foveon), so right off the bat you're working with handicap with respect to CMYK. However, that's not really the reason why this doesn't work... CMYK is a subtractive color model, it works by subtracting from white which is the presence of all colors. RGB is ...
