HotSpotter: Using a computer-driven photo-id application to identify sea turtles

Journal of Experimental Marine Biology and Ecology, 2021
Abstract Photo identification (PID) in animal studies has been a widely used method for identifying individuals of many species based on unique natural markings and patterns. The use of PID has facilitated investigations in which residency, home ranges, and growth rates have been assessed.

Photo‐ID‐based estimates of reproductive patterns in female harbor seals

Marine Mammal Science, 2007
AbstractVariations in reproductive patterns offer important insights into the dynamics of pinniped populations, but collecting data on reproduction for species that spend much of the breeding season in the water is problematic. We used land‐based photo‐identification techniques to collect individual‐based data on the timing of pupping, total pup ...

Pupil detection in photo ID

SPIE Proceedings, 2004
This paper presents a novel algorithm for locating pupils in a portrait image for ID card application. The proposed algorithm composed of three steps; skin detection, eye detection, and pupil detection. Skin detection for reducing the region of interest employs three modified single Gaussian skin models. In the second step, candidates of horizontal and
