torchmfbd 0.9.2

Multi-frame blind deconvolution with PyTorch

torchmfbd

Introduction

torchmfbd is a Python 3 package to carry out multi-object multi-frame blind deconvolution (MOMFBD) of point-like or extended objects, specially taylored for solar images. It is built on top of PyTorch and provides a high-level interface for adding observations, defining phase diversity channels and adding regularization. It can deal with spatially variant PSFs either by mosaicking the images or by defining a spatially variant PSF.

Features

• User-friendly API.
• Easy to use configuration file.
• Spatially invariant and variant PSFs.
• Easy-to-use regularization. The current version supports smooth solutions, and solutions based on the $\ell_1$ penalization of the isotropic undecimated wavelet transform of the object. Regularizations are easily extendable.
• Phase diversity.

Installation

Install it using pip install torchmfbd.
