Abstract
It is often desirable to evaluate an image based on its
quality. For many computer vision applications, a perceptually
meaningful measure is the most relevant for evaluation;
however, most commonly used measure do not map well to
human judgements of image quality. A further complication
of many existing image measure is that they require a reference
image, which is often not available in practice. In this
paper, we present a “blind” image quality measure, where
potentially neither the groundtruth image nor the degradation
process are known. Our method uses a set of novel
low-level image features in a machine learning framework
to learn a mapping from these features to subjective image
quality scores. The image quality features stem from natural
image measure and texture statistics. Experiments on a
standard image quality benchmark dataset shows that our
method outperforms the current state of art.
