Decentralized Attention Fails Centralized Signals: Rethinking Transformers for Medical Time Series

ICLR 2026oral

Accurate analysis of Medical time series (MedTS) data, such as Electroencephalography (EEG) and Electrocardiography (ECG), plays a pivotal role in healthcare applications, including the diagnosis of brain and heart diseases. MedTS data typically exhibits two critical patterns: **temporal dependencie…

Mind the Gap: Transferring Labels to Align Object Detection Datasets

CVPR 2026

Combining multiple object detection datasets offers a path to improved model generalisation but is hindered by inconsistencies in class semantics and bounding box annotations. Some methods to address this assume shared label taxonomies and address only spatial inconsistencies; others require manual

TRAINING-FREE TEST-TIME ADAPTATION WITH BROWNIAN DISTANCE COVARIANCE IN VISION-LANGUAGE MODELS

ICASSP 2026poster

Vision-language models suffer performance degradation under domain shift, limiting real-world applicability. Existing test-time adaptation methods are computationally intensive, rely on back-propagation, and often focus on single modalities. To address these issues, we propose Training-free Test-Tim…

SCOTCH and SODA: A Transformer Video Shadow Detection Framework

CVPR 2023poster

Shadows in videos are difficult to detect because of the large shadow deformation between frames. In this work, we argue that accounting for shadow deformation is essential when designing a video shadow detection method. To this end, we introduce the shadow deformation attention trajectory (SODA), a…

Video Adverse-Weather-Component Suppression Network via Weather Messenger and Adversarial Backpropagation

ICCV 2023poster

Although convolutional neural networks (CNNs) have been proposed to remove adverse weather conditions in single images using a single set of pre-trained weights, they fail to restore weather videos due to the absence of temporal information. Furthermore, existing methods for removing adverse weather…

RainFlow: Optical Flow Under Rain Streaks and Rain Veiling Effect

ICCV 2019poster

Optical flow in heavy rainy scenes is challenging due to the presence of both rain steaks and rain veiling effect, which break the existing optical flow constraints. Concerning this, we propose a deep-learning based optical flow method designed to handle heavy rain. We introduce a feature multiplier…
