Chimpanzees and humans have many things in common when it comes to facial expressions and facial structure; however, they also have many significant differences! Below is a series of imagery focusing on an action affected by the prominent brow ridge seen in chimpanzees: brow raiser – a frontalis action. Observe the key differences and similarities.
If you or your team are using open-source face tracking kits, figuring out what’s what can be challenging. Navigate the ambiguity with the FACS Translation Sheet!
In FACS, there are three main brow actions: inner brow raiser
outer brow raiser, brow lowerer. These actions and their combinations deform our brows into particular patterns, allowing us to identify different expressions.
We seem to subscribe to the popular oversimplification that machines are less biased than humans; however, if you are familiar with the ways in which machines are trained to read and focus on different aspects of data, you will know: It’s just not that simple.
The frontalis (forehead muscle that elevates your eyebrows) does not always follow the imagery presented in anatomy diagrams.
