computeAllSaliencyMaps

 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).

 See also batchSaliency, defaultSaliencyParams, makeSaliencyMap, initializeGlobal.
