Abstract
The paper elaborates on understanding, measuring and optimizing
perceived color quality of natural images. We introduce
a model for optimal color reproduction of natural
scenes which is based on the assumption that color quality
of natural images is constrained by perceived naturalness
and colorfulness of these images. To verify the model, a
few experiments were carried out where subjects estimated
the perceived 'naturalness', 'colorfulness' and 'quality' of
images of natural scenes. The judgments were related to
statistical parameters of the color point distribution across
the images in the CIELUV color space. It was found that
the perceptually optimal color reproduction can be derived
from this statistic within the framework of our model. We
specify naturalness, colorfulness and quality indices, describing
the observer's judgments. Finally, an algorithm
for optimizing perceived quality of color reproduction of
natural scenes is discussed.
