LIBERO-X: Robustness Litmus for Vision-Language-Action Models

RSS 2026poster

Reliable benchmarking is critical for advancing Vision–Language–Action (VLA) models, as it reveals their generalization, robustness, and alignment of perception with language-driven manipulation tasks. However, existing benchmarks often provide limited or misleading assessments due to insufficient e…

Reasoning-Driven Anomaly Detection and Localization with Image-Level Supervision

CVPR 2026

Multimodal large language models (MLLMs) have recently demonstrated remarkable reasoning and perceptual abilities for anomaly detection. However, most approaches remain confined to image-level anomaly detection and textual reasoning, while pixel-level localization still relies on external vision mod

Diffusion-4K: Ultra-High-Resolution Image Synthesis with Latent Diffusion Models

CVPR 2025poster

In this paper, we present Diffusion-4K, a novel framework for direct ultra-high-resolution image synthesis using text-to-image diffusion models. The core advancements include: (1) Aesthetic-4K Benchmark: addressing the absence of a publicly available 4K image synthesis dataset, we construct Aestheti…

Towards Training-free Anomaly Detection with Vision and Language Foundation Models

CVPR 2025poster

Anomaly detection is valuable for real-world applications, such as industrial quality inspection. However, most approaches focus on detecting local structural anomalies while neglecting compositional anomalies incorporating logical constraints. In this paper, we introduce LogSAD, a novel multi-modal…

Unveiling the Knowledge of CLIP for Training-Free Open-Vocabulary Semantic Segmentation

AAAI 2025technical

Training-free open-vocabulary semantic segmentation aims to explore the potential of frozen vision-language models (VLM) for segmentation tasks. Recent works reform the inference process of CLIP and utilize the features from the final layer to reconstruct dense representations for segmentation, dem…

Investigating Compositional Challenges in Vision-Language Models for Visual Grounding

CVPR 2024highlight

Pre-trained vision-language models (VLMs) have achieved high performance on various downstream tasks which have been widely used for visual grounding tasks in a weakly supervised manner. However despite the performance gains contributed by large vision and language pre-training we find that state-of…
