% computeAllSaliencyMaps - computes the saliency maps for many images.
%
% computeAllSaliencyMaps(imageFile,salmapFile,salParams,log_fid)
%    Computes the saliency maps for all images in imageFile.
%    This function is useful for batch processing many images.
%
%    imageFile - the file name of a .mat file with a vector of image
%       structures called 'images'. imageFile is relative to DATA_DIR,
%       the locations of the actual image files are relative to
%       IMG_DIR.
%    salmapFile - the file name of the file where the saliency maps
%       should be saved, relative to DATA_DIR.
%    salParams - the parameters for computing the saliency maps.
%    log_fid - a file identifier to write logging information to
%              (0 for no log info, 1 for stdout).
