William Freeman's group does lots of cool things in computational imaging and sensing, as well as ML. Fun fact: his group contributed to the formation of the first black hole image. Dr. Katie Bouman was his PhD student.
The whole field of remote photoplethysmography (rPPG) is quite interesting. I have implemented a couple algorithms, but they are quite "brittle" if you will, and only work well with certain videos. Many recent papers have introduced deep learning techniques. Hopefully these techniques are more robust to movement, skin color, lighting, and other natural conditions (unlike the usual computer vision/signal processing algorithms previously used).
