Mobile app for determining foliar damage caused by trophospheric ozone

This project is solving the Leaf Me Alone challenge.


Although the leaves serve as biomarkers for tropospheric ozone, scientist don't have an accurate idea of the extent of damage that has tropospheric ozone has done around the world. Data collection of large numbers of affected plants help to have a notion of whre the negative impact is generating the most.

What can people do for helping?

LeafO3 is an app that analyzes injured leaves by ozone on different plants and works like this:

1) You take a picture of an injured leaf using the app.

2) The app process the picture using an algorithm of image RGB segmentation and analyses it using clusters.

3) The damage it's calculated in percentage and classified in one of 7 classes of injury given by NASA.

4) The results are displayed on a map taking the geographic reference of where the picture was taken.

5)This can be used along NASA remote sensing products (satellital) to accurately determinate and understand the damage of tropospheric ozone around the world.

And that's how LeafO3 aims to contribute helping to solve a global problem with contributions of any person that has a smartphone.
