Peak Siggals -to -Noise Rasio (PSNR) adalah sebuah widely metric for assessing the kualite ty of compressed or reconstructucted images. Ini tidak membandingkan oreoriale imagee with figure figure tme to quantify revealtél distoriof noe reveibeleser.

Understanding PSNR

PSNR iS kalkulated based on the Meame Squared Error (MSE) between the orratul and the coversed imape. Te formula for PSNR is:

Pertama, FLT: 0 = FLT; 0 = PSNR = 10 * log 1; FI1; FLT: 1: 1 1; 10 1; FLT: 2: 2 MIS333; MIX; FL1; 3; 3 3; 2 1f; 1; 2: 1f; 4: 3 FLT; 3; 3 FLT; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3

Calculating PSNR Step -by- Step

To compute PSNR, follow these steps:

  • Kalkulate the MSE by averaging the ssared differences between corcorsesuai dengan piksel of the oratul and images.
  • Menentukan bahwa maksimal pixel value (e.g., 255 for 8- bit images).
  • Apply the PSNR formula using the MSE and MAX value.
