What is Sad,sae,satd,ssd,sse,mad,mae,msd,mse?

SAD (sum of Absolute difference) =sae (sum of Absolute error) is absolute error and

SATD (sum of Absolute transformed difference) i.e. Hadamard transform and then absolute sum

SSD (sum of squared difference) =sse (sum of squared error) is the sum of squares of the difference

MAD (Mean Absolute difference) =MAE(Mean Absolute Error) mean absolute difference

MSD (Mean squared difference) =MSE(Mean squared error) i.e. mean squared error
