### ExTools v9.3 (09-11-2022) ##
### ##
### by Dogway (Jose Linares) ##
### ##
### https://forum.doom9.org/showthread.php?t=182881 ##
### ##
###########################################################
###
### Pack of masktools2/removegrain replacement functions with...
### internal Expr() and many extra features.
### Generally works faster* than masktools2 counterparts for any given bitdepth.
### See performance notes (benchmarks over 1080p@16-bit).
###
### *Convolutions are slower than in masktools2/removegrain (SSSE3 vs AVX2)
###
### UV setting works similarly as in masktools2:
###
### 1: garbage
### 2: copy first
### 3: process
### 4: copy second
### 6: copy third (differs with masktools2's '5')
### 128: range_half
### x: custom value in 8-bit (bitdepth autoscaled) (1, 2, 3, 4, and 6 not available)
###
### fulls: Defines the source bitdepth scale (full/bitshift range) when converting from/to integer HBD formats (10, 12, 14, 16)
### ConvertBits() defaults to false for YUV, same in ExTools if frame properties are not present.
###
### Dependencies: AviSynth+ 3.7.2+ (https://forum.doom9.org/showthread.php?t=181351)
###
### Credits: Thanks to wonkey_monkey (David Horman) for Expr optimization tips

# modes:
# error = e = (predicted - observed) or (distorted - reference) = x - y
# ME - Mean Error or Bias. M(e). Measures additive bias in the error
# MAE - Mean Absolute Error -Manhattan or L1 norm-. M(|e|). Measures additive bias in the error but in a magnitude scale without sign
# PAE - Percentage of Absolute Error (not implemented)
# SMAE - Smooth Mean Absolute Error or Huber Loss. Same as MAE but less sensitive to outliers. It performs like MAE with low error and like MSE with high error
# MAD - Mean Absolute Deviation
# MAD2 - Median Absolute Deviation. median(|e-median(|e|)|). Similar to a standard deviation but more robust to outliers by replacing the means of squares with median of absolutes
# MSE - Mean Square Error / SSR / Quadratic Loss. Sometimes also erroneously labeled L2 norm. M(e^2) Gives more weight to large deviations or outliers
# MSLE - Mean Square Log Error. Gives less weight to large deviations or outliers. Useful when dealing with right skewed references
# RMSLE - Not implemented
# RMSE - Root Mean Squared Error / Standard Error / SRSS -Euclidean or L2 norm-. sqrt(M(e^2)). Gives more weight to large deviations or outliers. Same as MSE but rooted to normalize the units
# PSNR - Peak Signal-to-Noise Ratio
# CHAR - Charbonnier -L1-L2 loss-
# OkMSE - Euclidean Distance -RMSE- in OkLab
# RedMean - RedMean -sRGB fast metric-
# R2 - Coefficient of determination. Measure of the ratio of variability between the distorted and the reference
# ZTest - Two Sample Z-Test / Z-Score -Difference of Means of Distributions-
# SSIM - Structural SIMilarity
# MS-SSIM - Structural SIMilarity for Multi-Scale
# BSSIM - Structural SIMilarity for Blurred
# GMSD - Gradient Magnitude Similarity Deviation
# BUTT - Butteraugli psychovisual similarity index for DCT compression. Google's open source image metric tool tuned to high quality content (mainly between -q 90 to 95 in JPEG scale)
# MDSI - Mean Deviation Similarity Index. IQA model that utilizes gradient similarity (GS), chromaticity similarity (CS), and deviation pooling (DP)
# CAMBI - Contrast-Aware Multiscale Banding Index
