SPAR: Single-Pass Any-Resolution ViT for Open-vocabulary Segmentation

Naomi Kombol, Ivan Martinović, Siniša Šegvić +1

Foundational Vision Transformers (ViTs) have limited effectiveness in tasks requiring fine-grained spatial understanding, due to their fixed pre-training resolution and inherently…

Seal Your Backdoor with Variational Defense

Ivan Sabolić, Matej Grcić, Siniša Šegvić

We propose VIBE, a model-agnostic framework that trains classifiers resilient to backdoor attacks. The key concept behind our approach is to treat malicious inputs and corrupted la…

A Survey on Training-free Open-Vocabulary Semantic Segmentation

Naomi Kombol, Ivan Martinović, Siniša Šegvić

Semantic segmentation is one of the most fundamental tasks in image understanding with a long history of research, and subsequently a myriad of different approaches. Traditional me…
