IMAGing engINE, Tools for Application of Image Filters to Data Matrices

This package was built up to take numeric data matrices and apply image-filtering algoriths.

Algoriths used by imagine include median-filter and 2D-convolution based algoriths performed on Rcpp (C++) in order to speed up the application of this filters to large numeric matrices.


For installing imagine, as follows:


imagine performs algorithms written in Rcpp (called ‘engines’), ensuring a faster application of filters. At version 1.5.0, imagine includes four main engines, described as follows:

Main functions

There are 5 main functions and 2 wrappers:
