A three-Dimensional Look-up Table (3D LUT) is often used to transform one set of colors into another.

Abstract--Vision Foundation Models (VFMs) and Vision Language Models (VLMs) have revolutionized computer vision by providing rich semantic and geometric representations. This paper presents a comprehensive visual comparison between CLIP based and DINOv2 based approaches for 3D pose estimation in hand object grasping scenarios. We evaluate both models on the task of 6D object pose estimation and demonstrate their complementary strengths: CLIP excels in semantic understanding through language grounding, while DINOv2 provides superior dense geometric features. Through extensive experiments on benchmark datasets, we show that CLIP based methods achieve better semantic consistency, while DINOv2 based approaches demonstrate competitive performance with enhanced geometric precision. Our analysis provides insights for selecting appropriate vision models for robotic manipulation and grasping, picking applications.

We introduce DinoLizer, a DINOv2-based model for localizing manipulated regions in generative inpainting. Our method builds on a DINOv2 model pretrained to detect synthetic images on the B-Free dataset. We add a linear classification head on top of the Vision Transformer's patch embeddings to predict manipulations at a $14\times 14$ patch resolution. The head is trained to focus on semantically altered regions, treating non-semantic edits as part of the original content. Because the ViT accepts only fixed-size inputs, we use a sliding-window strategy to aggregate predictions over larger images; the resulting heatmaps are post-processed to refine the estimated binary manipulation masks. Empirical results show that DinoLizer surpasses state-of-the-art local manipulation detectors on a range of inpainting datasets derived from different generative models. It remains robust to common post-processing operations such as resizing, noise addition, and JPEG (double) compression. On average, DinoLizer achieves a 12\% higher Intersection-over-Union (IoU) than the next best model, with even greater gains after post-processing. Our experiments with off-the-shelf DINOv2 demonstrate the strong representational power of Vision Transformers for this task. Finally, extensive ablation studies comparing DINOv2 and its successor, DINOv3, in deepfake localization confirm DinoLizer's superiority. The code will be publicly available upon acceptance of the paper.

In this paper, we propose a generative multi-column network for image inpainting.

Nevertheless, it encounters challenges related to ill-posed problems, resulting in deviations between single model predictions and ground-truths. Ensemble learning, as a powerful machine learning technique, aims to address these deviations by combining the predictions of multiple base models.
