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
