ConfMatrix - Confusion Matrix
Thematic quality indices are provided to facilitate the
evaluation and quality control of geospatial data products
(e.g. thematic maps, remote sensing classifications, etc.). The
indices offered are based on the so-called confusion matrix.
This matrix is constructed by comparing the assigned classes or
attributes of a set of pairs of positions or objects in the
product and the ground truth. In this package it is considered
that the classes of the ground truth correspond to the columns
and that the classes of the product to be valued correspond to
the rows. The package offers two object classes with their
methods: 'ConfMatrix' (Confusion matrix) and 'QCCS' (Quality
Control Columns Set). The 'ConfMatrix' class of objects offers
more than 20 methods based on the confusion matrix. The 'QCCS'
class of objects offers a different perspective in which the
ground truth is considered to allow the values of the column
marginals to be fixed, see Ariza López et al. (2019)
<doi:10.3390/app9204240> and Canran Liu et al. (2007)
<doi:10.1016/j.rse.2006.10.010> for more details. The package
was created with 'R6'.
