Thinking Beyond Labels: Vocabulary-Free Fine-Grained Recognition using Reasoning-Augmented LMMs

CVPR 2026

Vocabulary-free fine-grained image recognition aims to distinguish visually similar categories within a meta-class without a fixed, human-defined label set. Existing solutions for this problem remain limited by either the usage of a large and rigid list of vocabularies or by the dependency on comple

All Languages Matter: Evaluating LMMs on Culturally Diverse 100 Languages

CVPR 2025highlight

Existing Large Multimodal Models (LMMs) generally focus on only a few regions and languages. As LMMs continue to improve, it is increasingly important to ensure they understand cultural contexts, respect local sensitivities, and support low-resource languages, all while effectively integrating corr…

Beyond Simple Edits: Composed Video Retrieval with Dense Modifications

ICCV 2025poster

Composed video retrieval is a challenging task that strives to retrieve a target video based on a query video and a textual description detailing specific modifications. Standard retrieval frameworks typically struggle to handle the complexity of fine-grained compositional queries and variations in…

CAMEL-Bench: A Comprehensive Arabic LMM Benchmark

NAACL 2025findings

Recent years have witnessed a significant interest in developing large multi-modal models (LMMs) capable of performing various visual reasoning and understanding tasks. This has led to the introduction of multiple LMM benchmarks to evaluate LMMs on different tasks. However, most existing LMM evaluat…

DriveLMM-o1: A Step-by-Step Reasoning Dataset and Large Multimodal Model for Driving Scenario Understanding

IROS 2025

While large multimodal models (LMMs) have demonstrated strong performance across various Visual Question Answering (VQA) tasks, certain challenges require complex multi-step reasoning to reach accurate answers. One particularly challenging task is autonomous driving, which demands thorough cognitive

Fann or Flop: A Multigenre, Multiera Benchmark for Arabic Poetry Understanding in LLMs

EMNLP 2025

Arabic poetry stands as one of the most sophisticated and culturally embedded forms of expression in the Arabic language, known for its layered meanings, stylistic diversity, and deep historical continuity. Although large language models (LLMs) have demonstrated strong performance across languages a

LlamaV-o1: Rethinking Step-by-step Visual Reasoning in LLMs

ACL 2025finding

Step-by-step reasoning is crucial for solving complex visual tasks, yet existing approaches lack a comprehensive framework for evaluating this capability and do not emphasize step-wise problem-solving. To this end, we propose a comprehensive framework for advancing multi-step visual reasoning in lar…

Time Travel: A Comprehensive Benchmark to Evaluate LMMs on Historical and Cultural Artifacts

ACL 2025finding

Understanding historical and cultural artifacts demands human expertise and advanced computational techniques, yet the process remains complex and time-intensive. While large multimodal models offer promising support, their evaluation and improvement require a standardized benchmark. To address this…

Composed Video Retrieval via Enriched Context and Discriminative Embeddings

CVPR 2024poster

Composed video retrieval (CoVR) is a challenging prob- lem in computer vision which has recently highlighted the in- tegration of modification text with visual queries for more so- phisticated video search in large databases. Existing works predominantly rely on visual queries combined with modi- fi…

Video Instance Segmentation via Multi-Scale Spatio-Temporal Split Attention Transformer

ECCV 2022poster

"State-of-the-art transformer-based video instance segmentation (VIS) approaches typically utilize either single-scale spatio-temporal features or per-frame multi-scale features during the attention computations. We argue that such an attention computation ignores the multi-scale spatio-temporal fea…
