Revisiting Modality Imbalance In Multimodal Pedestrian Detection

no code implementations24 Feb 2023 Arindam Das, Sudip Das, Ganesh Sistu, Jonathan Horgan, Ujjwal Bhattacharya, Edward Jones, Martin Glavin, Ciarán Eising

Multimodal learning, particularly for pedestrian detection, has recently received emphasis due to its capability to function equally well in several critical autonomous driving scenarios such as low-light, night-time, and adverse weather conditions.

Improving self-supervised pretraining models for epileptic seizure detection from EEG data

no code implementations28 Jun 2022 Sudip Das, Pankaj Pandey, Krishna Prasad Miyapuram

Traditional supervised learning algorithms are often limited by the amount of labeled data, especially in the medical domain, where labeling is costly in terms of human processing and specialized experts needed to label them.

Spatio-Contextual Deep Network Based Multimodal Pedestrian Detection For Autonomous Driving

no code implementations26 May 2021 Kinjal Dasgupta, Arindam Das, Sudip Das, Ujjwal Bhattacharya, Senthil Yogamani

Fusion of these two encoded features takes place inside a multimodal feature embedding module (MuFEm) consisting of several groups of a pair of Graph Attention Network and a feature fusion unit.

An End-to-End Framework for Unsupervised Pose Estimation of Occluded Pedestrians

no code implementations15 Feb 2020 Sudip Das, Perla Sai Raj Kishore, Ujjwal Bhattacharya

To tackle this problem for training the network, we make use of a pose estimation dataset, MS-COCO, and employ unsupervised adversarial instance-level domain adaptation for estimating the entire pose of occluded pedestrians.

Scale-Invariant Multi-Oriented Text Detection in Wild Scene Images

no code implementations15 Feb 2020 Kinjal Dasgupta, Sudip Das, Ujjwal Bhattacharya

Automatic detection of scene texts in the wild is a challenging problem, particularly due to the difficulties in handling (i) occlusions of varying percentages, (ii) widely different scales and orientations, (iii) severe degradations in the image quality etc.
