OITOOLS allows polychromatic and polytemporal imaging thanks to the powerful OptimPackNextGen library written by Eric Thiebaut.

ROTIR - Surface Imaging of Rotating Stars -
a Julia package written by Fabien Baron.

ROTIR allows surface imaging of rotating stars. The necessary physics is included to image rapid rotators or Roche surfaces. A binary module is in the works to allow imaging of evolving systems.

SQUEEZE
developed by Fabien Baron.
Visit its page.
SQUEEZE is designed to image complex astrophysical sources, while (optionally) modeling them simultaneously with analytic model (e.g. "SPARCO" mode). It can do polychromatic imaging provided the number of binned spectral channels remains low. SQUEEZE is based on Markov Chain Monte-Carlo (MCMC) exploration of the imaging probability space, and reconstructs images and associated error bars from standard OIFITS data. It leverages the Open Multi-Processing (OpenMP) application programming interface to implement simulated annealing and parallel tempering, in the hope of avoiding the local minima better than classic gradient-based image reconstruction software.

MiRA - Multi-aperture Image Reconstruction Algorithm -
a Yorick algorithm written by Eric Thiébaut.

Abstract (Bibcode:2008SPIE.7013E..1IT):
The sought image satisfies agreement with the input interferometric data and with some a priori image properties (positivity, normalization and regularization). The algorithm can cope with very limited amount of data; as an extreme case, MIRA is able to restore images without any Fourier phase information. This leads to the possibility to perform imaging with only 2 telescopes or when the phase closures are corrupted.
