You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: dbFnIlluminationContext.m
    path of file: ./repos/Image-Harmonization-Dataset-iHarmony4/Lalonde and Efros/colorStatistics/mycode/illuminationContext
    
    the code of the file until where you have to start completion: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% function dbFnLabHistogram(imgPath, imagesBasePath, outputBasePath, annotation, varargin)
%  Computes the L*a*b* histogram on different semantic parts of the image. At this point, sky and
%  ground are supported. These regions are obtained from Derek's photo-popup results. Saves
%  histograms in .mat files, and general information in the xml file.
% 
% Input parameters:
%
%   - varargin: Possible values:
%     - 'Recompute':
%       - 0: (default) will not compute the histogram when results are
%         already available. 
%       - 1: will re-compute histogram no matter what
