+function [SNRAll,SNRmiss] = SNRInpaintingPerformance(xRef,xObs,xEst,IMiss,DISP_FLAG)
+% Various SNR measures for inpainting performance
+%
+% Usage: [SNRAll,SNRmiss] = SNRInpaintingPerformance(xRef,xObs,xEst,IMiss,DISP_FLAG)
+%
+%
+% Inputs:
+%          - xRef - reference signal
+%          - xObs - observed signal
+%          - xEst - estimate signal
+%          - IMiss - location of missing data
+%
+% Outputs:
+%          - SNRAll - SNRAll(1) is the original SNR, between xRef and xObs; 
+%          SNRAll(2) is the SNR is the obtained SNR, between xRef and xEst
+%          - SNRmiss - the same as SNRAll but computed on the missing/restored
+%          samples only
