Package to apply MCR-ALS on CARS images

CARS Data

CARS Data is a package providing multivariate curve resolution algorithms and utilities functions for CARS cartographies. The package provides:

• a Simplisma algorithm implementation
• MCR-ALS based on pymcr package:
  • ALS and NNLS regressions
  • the classical normalization (sum-to-one) and non-negative constraints
  • a new segmentation constraint based on Chan-Sandberg-Vese algorithm
• fit unknown spectra onto fixed signature spectra using ALS or NNLS and apply MCR constraints on the results
• Autoencoders based on PyTorch packages.
