-
Gaussian Noise - Noise having PDF equal to the normal distribution. i.e. the pixel values that these noises can take are Gaussian distributed.
-
Impulse Noise - caused by sharp and sudden disturbances in the image signal. It usually occurs as white and black pixels in the image.
real-world noise (also known as blind noise)
- full-reference (FR) require full access to the reference video.
- Signal-to-Noise Ratio (SNR)
- Peak Signal-to-Noise Ratio (PSNR)
- Mean Squared Error (MSE), Structural SIMilarity (SSIM)
- Visual Information Fidelity (VIF)
- VSNR
- Video Quality Metric tools (VQM)
- reduced-reference (RR) techniques which need a set of coarse features extracted from the reference video.
