Efficient Labelling of Affective Video Datasets via Few-Shot & Multi-Task Contrastive Learning

1 code implementation4 Aug 2023 Ravikiran Parameshwara, Ibrahim Radwan, Akshay Asthana, Iman Abbasnejad, Ramanathan Subramanian, Roland Goecke

Whilst deep learning techniques have achieved excellent emotion prediction, they still require large amounts of labelled training data, which are (a) onerous and tedious to compile, and (b) prone to errors and biases.

A Weakly Supervised Approach to Emotion-change Prediction and Improved Mood Inference

no code implementations12 Jun 2023 Soujanya Narayana, Ibrahim Radwan, Ravikiran Parameshwara, Iman Abbasnejad, Akshay Asthana, Ramanathan Subramanian, Roland Goecke

Whilst a majority of affective computing research focuses on inferring emotions, examining mood or understanding the \textit{mood-emotion interplay} has received significantly less attention.

Visual Attention Methods in Deep Learning: An In-Depth Survey

no code implementations16 Apr 2022 Mohammed Hassanin, Saeed Anwar, Ibrahim Radwan, Fahad S Khan, Ajmal Mian

Inspired by the human cognitive system, attention is a mechanism that imitates the human cognitive awareness about specific information, amplifying critical details to focus more on the essential aspects of data.

CrossFormer: Cross Spatio-Temporal Transformer for 3D Human Pose Estimation

1 code implementation24 Mar 2022 Mohammed Hassanin, Abdelwahed Khamiss, Mohammed Bennamoun, Farid Boussaid, Ibrahim Radwan

3D human pose estimation can be handled by encoding the geometric dependencies between the body parts and enforcing the kinematic constraints.

Learning Discriminative Representations for Multi-Label Image Recognition

no code implementations23 Jul 2021 Mohammed Hassanin, Ibrahim Radwan, Salman Khan, Murat Tahtali

Multi-label recognition is a fundamental, and yet is a challenging task in computer vision.

Mitigating the Impact of Adversarial Attacks in Very Deep Networks

no code implementations8 Dec 2020 Mohammed Hassanin, Ibrahim Radwan, Nour Moustafa, Murat Tahtali, Neeraj Kumar

In it, a Defensive Feature Layer (DFL) is integrated with a well-known DNN architecture which assists in neutralizing the effects of illegitimate perturbation samples in the feature space.

Occlusion-Aware Human Pose Estimation with Mixtures of Sub-Trees

no code implementations3 Dec 2015 Ibrahim Radwan, Abhinav Dhall, Roland Goecke

The proposed method handles occlusions during the inference process by identifying overlapping regions between different sub-trees and introducing a penalty term for overlapping parts.
