% im=imread('test.bmp');
%quality=getQuality(im,codebook,codebookVIF,blocksizerow,blocksizecol,blockrowoverlap,blockcoloverlap)

% INPUTS :
% queryImg:         The distorted query image in uint8 format (color,if available or grayscale)
% codebook:         The codebook constructed by distorted image blocks (500*30)
% codebookVIF:      The VIF value of each code word in the codebook (500*1)
%blocksizerow:      98 (constant)
%blocksizecol:      98 (constant)
%blockrowoverlap:   0 (constant)
%blockcoloverlap:   0 (constant)
% OUTPUT :
% qualityScore : The quality score of the query image
