Face presentation attack detection (PAD) has become a clear and present threat for face recognition systems and many countermeasures have been proposed to mitigate it. In these countermeasures, some of them use the features directly extracted from well-known color spaces (e.g., RGB, HSV and YCbCr) to distinguish the fake face images from the...

Face presentation attacks have become a major threat against face recognition systems and many countermeasures have been proposed over the past decade. However, most of them are devoted to 2D face presentation attack detection, rather than 3D face masks. Unlike the real face, the 3D face mask is usually made of resin materials and has a smooth...

Adversarial reprogramming allows stealing computational resources by repurposing machine learning models to perform a different task chosen by the attacker. For example, a model trained to recognize images of animals can be reprogrammed to recognize medical images by embedding an adversarial program in the images provided as inputs. This attack...

Adversarial reprogramming allows repurposing a machine-learning model to perform a different task. For example, a model trained to recognize animals can be reprogrammed to recognize digits by embedding an adversarial program in the digit images provided as input. Recent work has shown that adversarial reprogramming may not only be used to abuse...

Cable-driven parallel robots can provide interesting advantages over conventional robots with rigid links; in particular, robots with a cable-suspended architecture can have very large workspaces. Recent research has shown that dynamic trajectories allow the robot to further increase its workspace by taking advantage of inertial effects. In our...

As a new event launched by our SPS, the 5-MICC has proved to be a success both in terms of public engagement and the quality of submissions, as seen from the large number of public votes cast for the three finalist videos. The only regret is that the participants, and especially the finalist teams, the organizing committee, and the judging...

In this paper, we analyze a spatial 3-degree-of-freedom cable-driven robot with a point-mass end-effector suspended by 3 cables. The kinematic and dynamic behaviour of this robot was investigated in previous works, in particular, the possibility of taking advantage of inertia forces on the end-effector to enlarge the robot workspace. Here, we...
