Photo-ID as a tool for studying and monitoring the endangered Saimaa ringed seal [PDF]

Endangered Species Research, 2016
Photo-identification (photo-ID) with camera traps was examined as a non-invasive method for studying and monitoring the endangered Saimaa ringed seal Phoca hispida saimensis.

Photo-ID and telemetry highlight a global whale shark hotspot in Palawan, Philippines. [PDF]

Sci Rep, 2019
AbstractThe Philippines is home to the second largest known population of whale sharks in the world. The species is listed as endangered due to continued population declines in the Indo-Pacific. Knowledge about the connectivity within Southeast Asia remains poor, and thus international management is difficult.

Near-perfect photo-ID of the Hula painted frog with zero-shot deep local-feature matching

Ecological Informatics
Accurate individual identification is essential to monitor rare species. Yet, invasive marking is often unsuitable for critically endangered species. Here, we evaluated state-of-the-art computer-vision methods for photographic re-identification of the ...

Redesigning photo-ID to improve unfamiliar face matching performance. [PDF]

Journal of Experimental Psychology: Applied, 2014
Viewers find it difficult to match photos of unfamiliar faces for identity. Despite this, the use of photographic ID is widespread. In this study we ask whether it is possible to improve face matching performance by replacing single photographs on ID documents with multiple photos or an average image of the bearer.

Skin lesions on common bottlenose dolphins (Tursiops truncatus) from three sites in the Northwest Atlantic, USA. [PDF]

PLoS ONE, 2012
Skin disease occurs frequently in many cetacean species across the globe; methods to categorize lesions have relied on photo-identification (photo-id), stranding, and by-catch data.

Rapid physiological colouration change is a challenge - but not a hindrance - to successful photo identification of giant sunfish (Mola alexandrini, Molidae)

Frontiers in Marine Science, 2023
Photo ID is a common tool in ecology, but has not previously been attempted for the ocean sunfishes (Mola spp., Molidae; ‘molids’). The technique, based on body patterns, could potentially be informative for studying the seasonal occurrence of giant ...

Matching Face Images Taken on the Same Day or Months Apart: the Limitations of Photo ID [PDF]

Applied Cognitive Psychology, 2013
SummaryIt is well‐established that matching images of unfamiliar faces is rather error prone. However, there is an important mismatch between face matching in laboratory and realistic settings. All of the currently available face‐matching databases were designed to establish the baseline level of unfamiliar face perception.

PhotoId-Whale: Blue whale dorsal fin classification for mobile devices.

PLoS ONE, 2020
Photo-identification (photo-id) is a method used in field studies by biologists to monitor animals according to their density, movement patterns and behavior, with the aim of predicting and preventing ecological risks.

A dataset of sea turtle occurrences around the Taiwan coast [PDF]

Biodiversity Data Journal, 2022
We describe a dataset of sea turtle sightings around the coast of Taiwan and its islands (Hoh and Fong 2022). This data collection was initiated by TurtleSpot Taiwan, a citizen-science project that collects sea turtle sighting data. This dataset includes

Viewers base estimates of face matching accuracy on their own familiarity: Explaining the photo-ID paradox [PDF]

Cognition, 2015
Matching two different images of a face is a very easy task for familiar viewers, but much harder for unfamiliar viewers. Despite this, use of photo-ID is widespread, and people appear not to know how unreliable it is. We present a series of experiments investigating bias both when performing a matching task and when predicting other people's ...
