Skepxels: Spatio-temporal Image Representation of Human Skeleton Joints for Action Recognition
Jian Liu, Naveed Akhtar, Ajmal Mian
Human skeleton joints are popular for action analysis since they can be easily extracted from videos to discard background noises. However, current skeleton representations do not…
Defense against Universal Adversarial Perturbations
Naveed Akhtar, Jian Liu, Ajmal Mian
Recent advances in Deep Learning show the existence of image-agnostic quasi-imperceptible perturbations that when applied to `any' image can fool a state-of-the-art network classif…
Viewpoint Invariant Action Recognition using RGB-D Videos
Jian Liu, Naveed Akhtar, Ajmal Mian
In video-based action recognition, viewpoint variations often pose major challenges because the same actions can appear different from different views. We use the complementary RGB…
Learning Human Pose Models from Synthesized Data for Robust RGB-D Action Recognition
Jian Liu, Naveed Akhtar, Ajmal Mian
We propose Human Pose Models that represent RGB and depth images of human poses independent of clothing textures, backgrounds, lighting conditions, body shapes and camera viewpoint…
