This article provides a comparison of a three methods
that can be used for calculating effective coverage of image
quality assessment database. The aim of this metric is to show
how well the database is filled with variety of images. For
each image in the database the Spatial Information (SI) and
Colorfulness (CF) metric is calculated. The area of convex hull
containing all the points on SI x CF plane is indication of total
coverage of the database, but it does not show how efficiently
this area is utilized. For this purpose an effective coverage was
introduced. An analysis is performed for 16 databases - 13
publicaly available and 3 artificial created for the purpose of
showing advantages of the effective coverage.
