Empirical Autopsy of Deep Video Captioning Frameworks
Nayyer Aafaq, Naveed Akhtar, Wei Liu +1
Contemporary deep learning based video captioning follows encoder-decoder framework. In encoder, visual features are extracted with 2D/3D Convolutional Neural Networks (CNNs) and a…
Adversarial Attack on Skeleton-based Human Action Recognition
Jian Liu, Naveed Akhtar, Ajmal Mian
Deep learning models achieve impressive performance for skeleton-based human action recognition. However, the robustness of these models to adversarial attacks remains largely unex…
Spherical Kernel for Efficient Graph Convolution on 3D Point Clouds
Huan Lei, Naveed Akhtar, Ajmal Mian
We propose a spherical kernel for efficient graph convolution of 3D point clouds. Our metric-based kernels systematically quantize the local 3D space to identify distinctive geomet…
Temporally Coherent Full 3D Mesh Human Pose Recovery from Monocular Video
Jian Liu, Naveed Akhtar, Ajmal Mian
Advances in Deep Learning have recently made it possible to recover full 3D meshes of human poses from individual images. However, extension of this notion to videos for recovering…
Label Universal Targeted Attack
Naveed Akhtar, Mohammad A. A. K. Jalwana, Mohammed Bennamoun +1
We introduce Label Universal Targeted Attack (LUTA) that makes a deep model predict a label of attacker's choice for `any' sample of a given source class with high probability. Our…
Octree guided CNN with Spherical Kernels for 3D Point Clouds
Huan Lei, Naveed Akhtar, Ajmal Mian
We propose an octree guided neural network architecture and spherical convolutional kernel for machine learning from arbitrary 3D point clouds. The network architecture capitalizes…
Going Deep in Medical Image Analysis: Concepts, Methods, Challenges and Future Directions
Fouzia Altaf, Syed M. S. Islam, Naveed Akhtar +1
Medical Image Analysis is currently experiencing a paradigm shift due to Deep Learning. This technology has recently attracted so much interest of the Medical Imaging community tha…
Spatio-Temporal Dynamics and Semantic Attribute Enriched Visual Encoding for Video Captioning
Nayyer Aafaq, Naveed Akhtar, Wei Liu +2
Automatic generation of video captions is a fundamental challenge in computer vision. Recent techniques typically employ a combination of Convolutional Neural Networks (CNNs) and R…
