Documentaton - GENERICS - DBFROMPATH

DB = DBFROMPATH(PATH) builds a database from the images in a file hierarchy. The directory PATH has one sub-directory for each visual category and, within each of those, a list of images from the corresponding category.

Many simple databases such as Caltech-4, Caltech-101 and Graz come in this format.

A few options may be used to control the process:

Shuffle [0]

  Shuffle images within each category.

Verbose [0]

  Set verbosity level.

FileFilter [.png|.jpg|.gif|.bmp|.pgm|.pbm|.ppm]

  Set a regexp to filter out unwanted image file. Use Verbose=1
  to see the default filter.

DirFilter [all directories]

  Set a regexp to filter otu unwanted directories. Use Verbose=1
  to see the default filter.
