Social Relation Recognition in Egocentric Photostreams
This paper proposes an approach to automatically categorize the social
interactions of a user wearing a photo-camera 2fpm, by relying solely on what
the camera is seeing. The problem is challenging due to the overwhelming
complexity of social life and the extreme intra-class variability of social
interactions captured under unconstrained conditions. We adopt the
formalization proposed in Bugental's social theory, that groups human relations
into five social domains with related categories. Our method is a new deep
learning architecture that exploits the hierarchical structure of the label
space and relies on a set of social attributes estimated at frame level to
provide a semantic representation of social interactions. Experimental results
on the new EgoSocialRelation dataset demonstrate the effectiveness of our
proposal.Comment: Accepted at ICIP 201
From Facial Parts Responses to Face Detection: A Deep Learning Approach
In this paper, we propose a novel deep convolutional network (DCN) that
achieves outstanding performance on FDDB, PASCAL Face, and AFW. Specifically,
our method achieves a high recall rate of 90.99% on the challenging FDDB
benchmark, outperforming the state-of-the-art method by a large margin of
2.91%. Importantly, we consider finding faces from a new perspective through
scoring facial parts responses by their spatial structure and arrangement. The
scoring mechanism is carefully formulated considering challenging cases where
faces are only partially visible. This consideration allows our network to
detect faces under severe occlusion and unconstrained pose variation, which are
the main difficulty and bottleneck of most existing face detection approaches.
We show that despite the use of DCN, our network can achieve practical runtime
speed.Comment: To appear in ICCV 201
