INHERITANCE

Data::TestImage::DB

DESCRIPTION

This module installs and provides metadata for the USC SIPI image database. This database is made up of 4 volumes: textures, aerials, miscellaneous, and sequences. By default, only the miscellaneous volume is installed.

METHODS

IMAGE_DB_VOLUME

    IMAGE_DB_VOLUME()

Returns a hash containing information about each of the volumes in the image database.

installed_volumes

    installed_volumes()

Returns an arrayref of strings indicating which volumes are installed.

get_metadata

    get_metadata()

Returns a hashref of metadata about all images in the database (even those not installed). This data includes the size, a textual description, and whether the image is 24 bpp color or 8 bpp monochrome.

get_image

    get_image($image_name)

Overrides "get_image" in Data::TestImage::DB to provide the default lookup by filename first and then if the image is not found, search the metadata text.

INSTALLATION

As discussed in Data::TestImage, installing further volumes can be done by setting the PERL_DATA_TESTIMAGE_INSTALL environment variable. The syntax for installing each volume is

    USC::SIPI=<volume>,<volume>,<volume>,...

where <volume> is one of the volume names as listed in "DESCRIPTION".

A shortcut for installing all volumes in the database is to use :all as the volume name, that is, set the environment variable to

    USC::SIPI=:all

and then install the distribution.

COPYRIGHT INFORMATION

The images in this database are not licensed for commercial use. For more information, see the database website.

The textual descriptions returned by "IMAGE_DB_VOLUME" and "get_metadata" are taken from the database catalog.
