redR (version 1.0.1)

error: Error measurements of images

Description

This function calculates error between two images

Usage

MSE(x, y = NULL)
MAE(x, y = NULL)
PSNR(x, y)

Arguments

x, y

cimg objects

Functions

• MSE: Mean Squared Error

• MAE: Mean Absolute Error

• PSNR: Peak Signal-to-Noise Ratio

Examples

# NOT RUN {
degraded.lenna <- degrade(lenna, noise = 0.05)
MSE(lenna, degraded.lenna)
MAE(lenna, degraded.lenna)
PSNR(lenna, degraded.lenna)
#alternatively it can be done like:
MSE(lenna - degraded.lenna)
MAE(lenna - degraded.lenna)
# }
