Three questions to ask the I3S team - 2

1. Let’s go back to the first question in blog 1. Why does the tool need user interaction and is it not fully automated?
Good question. As under water conditions vary enormously (e.g. light, distance, angle, particles in the water), automatic recognition is simply not reliable enough. It is our philosophy that software should support the human expert and never take important decisions on its own. I3S therefore only makes a ranking of best matches but leaves the final decision to you, the expert.
2. How much interaction is needed when using I3S?
We strongly believe the computer should assist the scientist and not take over its job. The most important prerequisite therefore, is ease of use. The interaction scenario for the user must be as simple as possible and the user should not be bothered with any complex processing that follows the interaction.
In general, annotation of a single image will require less than one or two minutes.
3. Tell us more about biometry.
The dictionary says ‘biometry is the analysis of biological data using mathematical and statistical methods’. It is also know as Biometrics or biometric authentication which refers to the identification of humans by their characteristics or traits. Biometrics is used in computer science as a form of identification and access control. For example finger prints in passports, facial recognition at the entrance of soccer stadions etc.
We will use the defenition ‘using unique body characteristics to identify species’.
Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. Biometric identifiers are often categorized as physiological versus behavioral characteristics. A physiological biometric would identify by one’s voice. Since we are focussing on identification from photographs, we will only deal with the physiological characteristics such as markings, spots, stripes, contours etc. as long as they are permanent. Since the under water conditions vary a lot, some user interaction is needed to get reliable results.
