Vessel segmentation algorithm times.

Comparison of segmentation times for vessel segmentation algorithms applied to a DRIVE database image. Timings are reported in the original papers, and details of computer specifications and implementation languages are given where these were made available. Four of the algorithms required training images to achieve their accuracy scores. Timings are given only for processing individual images; one-off initialisation stages required by some algorithms (e.g. to train a classifier) are not included. The IUWT algorithm made use of wavelet levels 2 and 3.
