lumos.brdf.tools.fit

lumos.brdf.tools.fit(data_file, model_func, bounds=None, p0=None, log_space=True, clip=0)[source]

Fits a model to experimental data.

Parameters:

  • data_file (str) – A path to a .csv file containing BRDF data. DESCRIBE FORMAT.

  • model_func (function) – A BRDF model to fit

  • bounds (tuple) – Bounds passed to scipy.optimize.curve_fit()

  • p0 (tuple) – Initial guess for parameters passed to scipy.optimize.curve_fit()

  • log_space (bool) – Whether or not to fit BRDF in log_space

  • clip (float) – Removes BRDF data below this cutoff from fitting
