About#
The Python Sparse data Analysis Package (PySAP) was developed as part of COSMIC, a multi-disciplinary collaboration between NeuroSpin, experts in biomedical imaging, and CosmoStat, experts in astrophysical image processing. The package was designed to provide state-of-the-art signal processing tools for a variety of imaging domains such as astronomy, electron tomography and magnetic resonance imaging (MRI). The first release of PySAP was presented in Farrens et al. [2020].
Structure#
PySAP is comprised of several core modules, namely:
Sparse2D: a collection of sparse image transforms written in C++
ModOpt: a library of modular optimisation algorithms
Application-specific plug-ins
PySAP provides Python bindings to the C++ libraries, shared tools and a common interface for all of the plug-ins.
Plug-ins#
PySAP plug-ins are application-specific tools designed for a given imaging domain. Plug-ins combine ModOpt algorithms with image transforms to solve complex inverse problems.
Note
New plug-ins can be developed using the PySAP plug-in template.
The plug-ins currently available in PySAP are:
PySAP-Astro: astrophysical image processing
PySAP-ETomo: electron tomography image processing
PySAP-MRI: magnetic resonance image processing
