I was trying to manually code something like this in Python, but it's great to see such a software already exists and is in the public domain. Great tutorials!
all the numerical values are very specific to your images...! This approach to image processing is very dependent on lighting and leaves color, so any other image will take a long time to find the effective values! :(
I think you just play with the sliders until the appropriate areas are selected. There is no one-size-fits-all threshold values. If you need a more controlled environment, averaging multiple leaves pictured in controlled conditions (like in a lab photography setup with controlled lighting) would make these values more consistent. You still will have to play around to find these values.
