Image Error Measurements

main executing reference usage: usage_errorMeasurementsOfImages.m
-----------------------------------------------------------------------------
The objective is to measure the differences between 2 images, and measurement of image quality.
1. Mean squared error, MSE
2. Root Mean squared error, RMSE
3. Peak signal to signal noise ratio, PSNR
4. Mean absolute error, MAE
5. Signal to signal noise ratio, SNR
6. Universal Image Quality Index
7. Enhancement Measurement Error, EME
8. Pearson Correlation Coefficient

Sample output:
--------------
PSNR = +13.81915 dB
MSE = 108.53790
RMSE = 10.41815
Universal Image Quality Index = 0.16077
EME (original image) = 14.50599
EME (noisy image) = 8.48040
PearsonCorrelationCoefficient (originalImage vs noisyImage) = 30959.27033
PearsonCorrelationCoefficient (originalImage vs originalImage) = 50624.00000
SNR = -10.28091 dB
MAE = 19.82882
