Abstract
The scaled Peak Signal-to-Noise Ratio (PSNR) method scales PSNR to 1.00 or 100% from infinite decibel values. The PSNR describes the ratio between the maximum possible value (power) of a signal and the power of signal's noise. Noise affects the quality of its representation. Signals dynamically fluctuate from the smallest to largest possible quantity. The unsettled range to maximum from minimum values of the noise is unknown. Therefore, the PSNR usually forms on a logarithmic way (log) of describing a ratio, the decibel (dB). The dB is able to gauge the level of power, communication signal (intensity or voltage), sound pressure, and intensity of several other items including images.
