Description

This database contains photometric images sets (normally 8 at a time) which are primarily concerned with surface invariant texture classification algorithms. It was developed by  Jerry Wu for his PhD.

It contains 30 real textures of 3D rough surfaces taken by the digital camera, with different surface orientations and under controlled illumination conditions. There are currently 1680 images in the database.

Organization

The image files are named according to the following format:

[Investigation].[texturename].[rotation].[slant].[tilt].[format]


EXAMPLE: 0.an1.30.45.90.bmp

The image an1 has been captured under the illumination condition with the slant angle of 45° and the tile angle 90° at the surface orientation angle of 30°.

Equipment

All the images in the texture database where captured using the Vosskuhler CCD 1300LN digital camera (specifications of this camera can be accessed via www.vdsvossk.de). This was used with a Matrox PC-SIG framestore. The light source is a filament tube with a mask, which is fixed on an arm in order to move to the specified slant and tilt angle. The general capture setup is illustrated below.
