A spatial extension method of Weber-Fechner Law

Based on the Weber-Fechner Law and decomposition method of image space vector, a space similarity analysis model of Weber-Fechner Law is proposed by analyzing space vector structure similarity. We explore the vision feeling of background brightness, contrast similarity and independence component, and establish new measurement of image quality. It is found that space model is more matching with subjective vision feeling and lowers complex and uncertain of image quality assessment from experimentation result. The conclusion is valuable for setting up new image quality assessment.
