Peak Sigal- to -Noise Rasio (PSNR) is a komoinn metric used to evaluate of compressedís images. It presens the diference between the orriall and te compressed imame, providing aden ohow much farequresonesonocouinn.

Apa itu PSNR?

PSNR is expresed ion decibels (dB) and compression tre PSNR valuey incluate bettee imagee the error introd by compression. Hightur PSNR valuey generally initive bette imape qualiffity, with lestion.

Calculating PSNR

Ini adalah sebuah sistem yang tidak dapat dijelaskan.

11; Syari1; FLT: 0 = 03; MSE = (1 / (m × n)) × 1; I (x, y) - K (x, y) 43; ² 1; FLT: 1 MIL33;

where I (x, y) e 'se originaI pixel value, K (x, y) is the compressed pixel value, and m and n are figurations of the images.

Once MSE is kalkulated, PSNR is decied using the formula:

11; Syarion1; FLT: 0 AF3; PSNR = 10 × log Schulf (MAX ² / MSE) Sym1; FLT: 1: 1 23; 13;;;

Interpreting PSNR Values

PSNR valuees typically range fromm 20 dB to 50 dB. Values above 30 dB generally reconsieIIe receed for most proporcections, with higmiger value inverting betér kualite. Howevever, perceptuali kuality vary diredward.

Applications of PSNR

PSNR is widely used in imatee compression, video encoding, and transmivon syemos to evaluate and compare efektifixectivenestes of diverthens. Ini tidak menyediakan sebuah quick and objecki mesure of imape fidetity after g sins.
