Walk like an Egyptian: computer vision and walking identification

Researchers from the University of Malaga and Cordoba have studied gait recognition. Gait is the pattern of movement of the limbs of animals, including humans, during locomotion over a solid substrate. The goal of gait recognition is to identify people by the way they walk. This biometric approach is performed at a distance, and does […]

Can we still avoid automatic face detection?

After decades of research, automatic face detection and recognition systems are now reliable and widespread. Of course, the result of this is that the users who wish to avoid automatic recognition are becoming less capable of doing so. We currently live in a technology-dependent society, where everyone carries a cellphone with a camera in their […]

Images don’t lie: rank learning

The task of ranking search results automatically is a multibillion dollar machine-learning problem. Traditional models optimize over a few hand-crafted features based on the item’s text. Recently, researchers have created a multimodal learning method that combines this traditional features with visual semantic features transferred from a deep convolutional neural network. They have tested their model […]

Lie to me: reading hidden emotions

IEEE researchers have studied micro-expressions: rapid, involuntary facial expressions which reveal emotions that people do not intend to show. This is of extreme importance in forensic science and psychotherapy, and we all remember the TV show Lie to me, which focused on these micro-expressions (MEs). Unlike the pompous TV shows, real-life analysis of spontaneous MEs […]
