Abstract

Visual noise is a metric for measuring the amount of noise perception in images taking into account the properties of the human visual system (HVS). A visual noise measurement method is specified in Annex B of ISO 15739, which has been used as a useful measurement metric over the years since its introduction. As several issues have been questioned recently, it is now being investigated for revision involving changes to the CSF, color space used for rms noise value measurements, and visual noise formula combining rms values in three color channels. To derive visual noise formula involving color noise weighting coefficients representing HVS sensitivity to noise, subjective experiments using simulated luminance and color noise images were done. The improvement of calculation stability and HVS correspondence was verified using simulation and real camera images under various conditions. Finally, subjective experiments using real camera images were performed to validate the revised method and update the color noise coefficients considering practical measurement cases.
