1. A method of detecting sky in a digital color image having pixels, the method comprising:
- a) identifying pixels from the digital color image representing an initial sky region;
b) developing a model based on the identified sky pixels, wherein such model is a mathematical function that has inputs of pixel position and outputs of color; and
c) using the model to operate on the digital color image to classify additional pixels not included in the initial sky region as sky.
