Dynamic Flat-Field Correction

This package implements the dynamic flat-field correction.

Brief description

The method described here consists of two separate steps:

1. Initially, reference flat-fields and dark-fields are acquired and PCA is used to obtain the most relevant principal components of the flat-field dataset.

2. During data acquisition with a sample, the effecitve flat- field is computed for each individual frame as a weighted sum of principal components, while the weights subject to minimize the total variance of the corrected image.
