Abstract
Image quality metrics have been widely used in imaging systems
to maintain and improve the quality of images being processed and
transmitted. Due to the close relationship between image quality and human
visual perception, both computer scientists and psychologists have
contributed to the development of image quality metrics. In this paper,
a novel image quality metric using a colour appearance model is proposed.
After the physical colour stimuli of the images being compared
are transformed into perceptual colour appearance attributes, the distortion
measures between the corresponding attributes are used to predict
the subjective scores of image quality, by use of data-driven models:
Multiple Linear Regression (MLR), General Regression Neural Network
(GRNN) and Back-Propagation Neural Network (BPNN). Based on the
data-driven model used, we have developed three image quality metrics,
CAM MLR, CAM GRNN and CAM BPNN. The experiments have
shown that the performance of CAM BPNN is better than the wellknown
image quality metric SSIM.
