The aim is to integrate colorfulness into an image quality evaluation framework for assessing image processing effects.
Conducted a psychophysical category scaling experiment to rate colorfulness in natural images.
Participants rated images across 7 categories of colorfulness.
A metric was developed to correlate ratings with experimental data, achieving over 90% correlation.
The new metric effectively quantifies colorfulness, allowing real-time application on video streams.
Correlation of over 90% with experimental data indicating strong validity of the proposed method.
