Recently, the term “ReID,” short or Re-Identification has apprarently appeared in the Animal Biometrics community, apparently from the “human domain,”  that is to say that it is a term used in studies of human identification.  To put this in perspective, Visual ID or visual identification, equivalently, PhotoID and Individual ID are tems used in  “Animal…

 The Design and Use of MIT Sloop Retrieval Engine for Animal Biometrics Sai Ravela, MIT  Abstract: Identifying individuals in photographs of animals collected over time is a non-invasive approach for ecological monitoring and conservation. This paper describes the design and use of Sloop (sloop.mit.edu), for animal biometrics incorporating crowd-sourced relevance feedback. Sloop’s iterative retrieval strategy…

One problem we’ve encountered is the effect of glare in the images analyzed by SLOOP. Here we reduce glare by masking the reflections and inpainting the patterns. Check out our results.

The objective is to decide whether two images are identical within some acceptable variability. Here we use scale-cascaded alignment to reduce the chance that the program will incorrectly morph an image thereby creating a false match.

It was fun presenting Sloop at the Microsoft Faculty Summit! https://www.microsoft.com/en-us/research/event/latin-american-faculty-summit-2014/#!speakers-abstracts

Chelsea Finn, MIT Earth Signals and Systems Group. Cambridge, MA Behind the scenes of the Sloop system are several computer vision algorithms that match images of individual animals across hundreds or thousands of photos . The most recent species being added to the system is the whale shark (Rhincodon typus; Sloop-WS). The goal of each of…

Nayna Vyas-Patel Traditional methods of identifying insects is intensely time consuming and a task best left to highly trained and experienced taxonomists. One mosquito can look very much like another, a ladybird or bee with deadly properties can appear to be one species, when in fact it is an aggressive intruder, masquerading as a more…
