Outex database contains surface textures and natural scenes

Collection of surface textures

The collection of surface textures is expanding continuously. At this very moment the database contains 320 surface textures, both macrotextures and microtextures.

Surface categories and the number of textures in each category:

• barleyrice: 11
• canvas: 46
• cardboard: 1
• carpet: 12
• chips: 23
• crushedstone: 8
• flakes: 10
• flour: 13
• foam: 4
• fur: 12
• granite: 10
• granular: 3
• gravel: 7
• groats: 7
• leather: 5
• mineral: 6
• paper: 10
• pasta: 6
• pellet: 4
• plastic: 47
• quartz: 6
• rubber: 1
• sand: 5
• sandpaper: 8
• seeds: 13
• tile: 7
• wallpaper: 20
• wood: 12
• wool: 2

Many textures have variations in local color content, which results in challenging local gray scale variations in intensity images. Some of the source textures have a large tactile dimension, which can induce considerable local gray scale distortions. Each source texture is imaged according to the procedure described in Image database/acquisition, hence the current database of surface textures comprises of 27054 images, in both 24-bit RGB and 8-bit gray scale, totaling about 40 GB of disk space.

Collection of natural scenes

Construction of the database of natural scenes is at an early stage. We have captured scene images of 1712x1368 pixels in size with a Olympus Camedia C-2500 L digital camera.
