Python code to fit a gaussian mixture model to an image using various techniques.

• Expectation Maximization.
• Levenberg-Marquardt optimization
• MCMC, of the affine invariant variety.

Under the hood, C librares are used for speed.

The workhorses modules are

• gmix_image.gmix_fit
  • maximum likelihood fitters
• gmix_image.gmix_mcmc
  • MCMC fitters
• gmix_image.em
  • EM fitters
