PD is set to the appropriate path delimiter for your operating system ('/' for Unix variants, '\' for MS Windows). IMG_EXTENSIONS is a cell arrays with possible extensions for image files. DEBUG_FID is the file identifier for debugMsg output. It is by default set to 0. Set to 1 for stdout or to the fid of a text file that is open for write access. BASE_DIR is set to ''. IMG_DIR is set to ''. DATA_DIR is set to ''. TMP_DIR is set to the Matlab standard tempdir. In the SaliencyToolbox, all paths to images are assumed to be relative to IMG_DIR, and all paths to data files relative to DATA_DIR. If no base directory is supplied at the call of initializeGlobal, all these paths are empty, and all image paths will have to be absolute paths or relative to the current directory. Setting a base path allows for more flexibility in migrating data to other locations in the path, because paths will be relative to the base path, whch can be different on different machines, for example. initializeGlobal(base_dir) does the same as above, except: BASE_DIR is set to base_dir and created if it doesn't exist. IMG_DIR is set to base_dir/img and created if it doesn't exist. DATA_DIR is set to base_dir/data and created if it doesn't exist. TMP_DIR is set to base_dir/tmp and created if it doesn't exist.
