phenofit combine the strength of timesat and phenopix, and provide a practical snow elimination method, a simple and stable growing season dividing methods, 7 curve fitting methods and 4 phenology extraction methods. We add parameters boundary for every curve fitting methods, which make curve fitting parameters much stable and meaningful. We also combine R optimx package to select best optimization method for different curve fitting methods.
