MEFA-MS: attention-based U-Net for pedestrian and vehicle detection

Yoann Dupas, Olivier Hotel, Grégoire Lefebvre, Christophe Cérin

MEFA-MS revisits early fusion with a U-Net architecture and spatial and channel attention. It aims to preserve detection quality while reducing inference cost.

Key contribution : An attention-based encoder-decoder, evaluated against MEFA on DENSE with RT-DETR.

Towards a Generalizable Fusion Architecture for Multimodal Object Detection

Jad Berjawi, Yoann Dupas, Christophe Cérin

FMCAF combines frequency-domain filtering and cross-attention to fuse RGB and infrared images. It is evaluated on low-light pedestrian detection and aerial vehicle detection.

Key contribution : Fusion studied in two different settings: LLVIP and VEDAI.

MEFA: Multimodal Image Early Fusion with Attention Module for Pedestrian and Vehicle Detection

Yoann Dupas, Olivier Hotel, Grégoire Lefebvre, Christophe Cérin

MEFA uses attention to fuse visible, infrared and LiDAR images before detection. It is studied with YOLOv8 and RT-DETR, including rainy and foggy conditions.

Key contribution : An upstream fusion module that works with existing single-modality detectors.

Empreinte Énergétique de YoloV8 pour la Détection de Piétons et de Véhicules

Yoann Dupas, Olivier Hotel, Grégoire Lefebvre, Christophe Cérin

This conference contribution focuses on the energy footprint of YOLOv8 for pedestrian and vehicle detection.

Key contribution : Bringing energy use into the evaluation of object detectors.
