function [Xdenoised] = CVBM3D(Xnoisy, sigma, Xorig)
%  CVBM3D denoising of RGB videos corrupted with AWGN.
%
%
%  [Xdenoised] = CVBM3D(Xnoisy, sigma, Xorig)
%
%  INPUTS:
%
%   1)  Xnoisy --> Either a filename of a noisy AVI RGB uncompressed video (e.g. 'SMg20.avi') 
%                  or a 4-D matrix of dimensions (M x N x 3 x NumberOfFrames)
%                  The intensity range is [0,255]!
%   2)  Sigma -->  Noise standard deviation (assumed intensity range is [0,255])
%
%   3)  Xorig     (optional parameter) --> Filename of the original video
%
%  OUTPUT: .avi files are written to the current matlab folder
%
%   1) Xdenoised --> A 4-D matrix with the denoised RGB-video
%
%  USAGE EXAMPLES:
%   1) To denoise a video:
%      CVBM3D('SMg20.avi', 20)
%
%   2) To denoise a video and print PSNR:
%      CVBM3D('SMg20.avi', 20, 'SM.avi')
%
%   1) To denoise a 4-D matrix representing a noisy RGB video:
%      CVBM3D(X_4D_matrix, 20)
