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).
