Marking Bloodstain Ellipses

Dear Colleagues,

We are currently working on a large study where we are asking for 15-20 minutes of your time to mark ellipses on 18 images of bloodstains.

We are looking for participants of all levels to better understand how well humans perform at marking bloodstain ellipses where errors are most prevalent.

All images are marked using an online app and all that is necessary is a web browser like Chrome, Internet Explorer or Safari and a computer mouse. No personal information will be published and all data will be aggregated anonymously.

This exercise is rather straight forward and includes a 2-minute YouTube video tutorial which you are encouraged to view before you start. Should there be any problems, feel free to reach out to us.

Our sincerest thanks,
