Person Re-Identification Using Deep Learning

Person re-identification is a critical task in video surveillance. Person re-identification problem can be defined as recognizing the same person across a bunch of cameras with overlapping fields of view with the given query image.

Remote Heart Rate Estimation

Heart Rate (HR) is an important physiological sign since we can monitor our cardiac activity through it and cardiac diseases are directly connected to the human life. Video-based HR estimation is a safe and low-cost remote HR estimation technique originated from the Photoplethysmography. By analyzing the human face video, we can estimate the small varaition underneath the skin which carries the HR signal.
