ECE Seminar: Seeing the Invisibles: Micro-Signal Analytics for Digital Forensics & Health

Visual sensing and processing have undergone a significant growth in the recent decades. Complementing the R&D dealing with visible signals are those exploiting a variety of nearly invisible ones. These "micro-signals" are typically an order of magnitude lower in strength or scale than the dominant ones. They are ubiquitous, and often removed or ignored as nuances. Increasingly, it has been found that many micro-signals help us connect the physical world with the digital cyberspace, offering beneficial information that would otherwise harder to obtain. This talk will provide an overview of the research advances on several representative types of micro-signals, discussing how to extract, analyze and harness them, and presenting several applications in security, digital humanity, and health.
