Identification of Individual Spotted Salamanders

Lunch will be served at noon.


Amphibians such as spotted salamanders pose challenges to scientists who would like to physically tag them for purposes of tracking. Fortunately, there has been a great deal of work in recent years on non-invasive tracking procedures, including photographic capture. The challenge, then, is to identify individuals from digital images and to do so computationally. In this talk I will discuss the challenges of extracting useful data from images of spotted salamanders. I will describe and compare two algorithms for identifying individuals and will discuss why "obvious" approaches that mimic the spot counting used by humans do not perform well.
