N-CRiPT Public Seminar: Privacy-aware Analytics for Human Attributes from Images
Jointly presented with SGInnovate
Speaker: Professor Mohan Kankanhalli
Date & Time: Thursday 29 April, 4.00pm – 5.00pm
Analyzing human attributes such as emotions, gender and age in images and videos is very important for many applications. Many existing methods perform well by utilizing human faces information. However, face images raise serious privacy concerns as they reveal people’s identity. We describe our on-going research on the problem of human attributes prediction under privacy-preserving conditions. We first did a human study of age, gender, and emotion prediction in images under various identity preserving scenarios – obfuscating eyes, lower face, head or the full face. Motivated by this human study, we developed a multi-tasking deep learning model for context-guided human attributes prediction and we present its results. We will end with a general discussion on privacy concerns related to image and video data analytics.
