Crack Detection – ULTIR
http://www.mjobyrne.com/crack-detection
The ROC curves for all of the specimens under a certain lighting and turbidity condition are averaged to produce a curve representative of the overall performance of a particular technique at that lighting and turbidity condition. This results in 9 curves for each technique, which are plotted below:. Lighting level 1, 100 lux. Lighting level 2, 1,000 lux. Lighting level 3, 10,000 lux. Turbidity level 1, 0 NTU. Turbidity level 2, 6 NTU. Trbidity level 3, 12 NTU.

About ULTIR – ULTIR
http://www.mjobyrne.com/about-ultir
This repository contains three categories. These relate to:. 2) Surface Damage Detection. 3) 3D Shape Recovery using Stereo-vision. The imagery contained within each category were captured under three lighting levels and three turbidity levels, resulting in nine images for each specimen. These varying levels portray the conditions that may be encountered in an underwater inspection setting. Pictures can be freely reproduced as long as credit is provided.

The first part of the image name reveals the width of the crack. The controlled specimens have crack widths of either 1 mm, 3 mm, or 5 mm. The second part of the name describes the nature of the crack. It provides information on attributes such as whether a crack is straight or curved. The third part indicates the lighting level. L1, L2, and L3 denote low (100 lux), medium (1,000 lux), and high (10,000 lux) light levels respectively. Section 2: Surface Damage. Section 3: Shape Information (Stereo Imagery).
