%h_i stands for the input image histogram.
% d as feature distance.
% d must be within {1,2,...,255} range.
    out_hist=zeros(ceil(256/d),1);% Initialization
    % merge the symbols with respect to the feature distance:
    for r=1:uint8(ceil(256/d))
        out_hist(r,1)=sum(h_i((r-1)*d+1:r*d,1));
