The use of the computer-assisted measurements utility
Author & date of last revision: admin on 20 November 2011
We compare traditionally used straight linear shell measurements, with "surface" and "perimeter" measurements, obtained using image analysis software. A preliminary assessment was made on four species from the family Enidae. We evaluated the quality of all measurements used to identify those of greatest taxonomic value. The results obtained demonstrate that the use of computer-assisted measurements provide more reliable and less variable data than traditional ones.
