Paper Abstract

After a short survey of some other measures of perceived image quality, the recently proposed square root integral (SQRI) is described. Special attention is paid to the way in which this metric takes the effect of various display parameters into account. Experimental data on subjective image quality at varying resolution, addressability, luminance and display size are compared with predictions by the square root integral. From the comparison it appears that there is a linear relation between subjective image quality and SQRI value.
