Columbia University, the University of Maryland, and the Smithsonian Institution are working on visual recognition software to help identify species from photographs. Leafsnap is the first in a series of electronic field guides being developed to demonstrate this new technology.
This free mobile app helps identify tree species from photographs of their leaves. Leafsnap currently includes the trees of the Northeast and will soon grow to cover the trees of the entire continental United States.

The realization of Leafsnap was possible thanks to the collaboration between Peter Belhumeur (Columbia University), David Jacobs (University of Maryland), and John Kress (Smithsonian Institution).

The high quality photographs on the website leafsnap.com and in the app were made by the the not-for-profit nature photography group Finding Species.

Global Health

Declaring an emergency is a dirty work, but someone has to do it. When facing a serious threat to global public health, even if complete evidence is lacking, someone has to take the responsibility to push the red button that activates a chain of coordinated actions (such as cooperation among states and research of vaccines). Choosing to do this, the risk of giving a false alarm is unavoidable. On the other side, one could decide to wait until something more is known, with the awareness that, in this way, it is possible to act when it is too late.
