MJ-Bench: Is Your Multimodal Reward Model Really a Good Judge for Text-to-Image Generation?

NeurIPS 2025poster

While text-to-image models like GPT-4o-Image and FLUX are rapidly proliferating, they often encounter challenges such as hallucination, bias, and the production of unsafe, low-quality output. To effectively address these issues, it is crucial to align these models with desired behaviors based on fee…

3D Human Keypoints Estimation From Point Clouds in the Wild Without Human Labels

CVPR 2023poster

Training a 3D human keypoint detector from point clouds in a supervised manner requires large volumes of high quality labels. While it is relatively easy to capture large amounts of human point clouds, annotating 3D keypoints is expensive, subjective, error prone and especially difficult for long-ta…

NeMo: Learning 3D Neural Motion Fields From Multiple Video Instances of the Same Action

CVPR 2023highlight

The task of reconstructing 3D human motion has wide-ranging applications. The gold standard Motion capture (MoCap) systems are accurate but inaccessible to the general public due to their cost, hardware, and space constraints. In contrast, monocular human mesh recovery (HMR) methods are much more ac…

Unsupervised Discovery of the Long-Tail in Instance Segmentation Using Hierarchical Self-Supervision

CVPR 2021poster

Instance segmentation is an active topic in computer vision that is usually solved by using supervised learning approaches over very large datasets composed of object level masks. Obtaining such a dataset for any new domain can be very expensive and time-consuming. In addition, models trained on cer…
