Comment (by Nikos Alexandris):

 As for the histogram matching routine, here two related open source
 examples (written in Rust):

 https://github.com/jblindsay/whitebox-
 tools/blob/266c939ad236c16503b088d2faa4500362912fef/src/tools/image_analysis/histogram_matching.rs

 and

 https://github.com/jblindsay/whitebox-
 tools/blob/266c939ad236c16503b088d2faa4500362912fef/src/tools/image_analysis/histogram_matching_two_images.rs

 My understanding is that the implementation bases upon (64-bit) floating
 point.
