An Intra- and Cross-frame Topological Consistency Scheme for Semi-supervised Atherosclerotic Coronary Plaque Segmentation

ICASSP 2025accepted

Enhancing the precision of segmenting coronary atherosclerotic plaques from CT Angiography (CTA) images is pivotal for advanced Coronary Atherosclerosis Analysis (CAA), which distinctively relies on the analysis of vessel cross-section images reconstructed via Curved Planar Reformation. This task pr…

Reconstructing Hands in 3D with Transformers

CVPR 2024poster

We present an approach that can reconstruct hands in 3D from monocular input. Our approach for Hand Mesh Recovery HaMeR follows a fully transformer-based architecture and can analyze hands with significantly increased accuracy and robustness compared to previous work. The key to HaMeR's success lies…

Coarse-to-Fine Covid-19 Segmentation via Vision-Language Alignment

ICASSP 2023accepted

Segmentation of COVID-19 lesions can assist physicians in better diagnosis and treatment of COVID-19. However, there are few relevant studies due to the lack of detailed information and high-quality annotation in the COVID-19 dataset. To solve the above problem, we propose C2FVL, a Coarse-to-Fine se…

Towards A Richer 2D Understanding of Hands at Scale

NeurIPS 2023poster

As humans, we learn a lot about how to interact with the world by observing others interacting with their hands. To help AI systems obtain a better understanding of hand interactions, we introduce a new model that produces a rich understanding of hand interaction. Our system produces a richer output…

EPIC-KITCHENS VISOR Benchmark: VIdeo Segmentations and Object Relations

NeurIPS 2022accept

We introduce VISOR, a new dataset of pixel annotations and a benchmark suite for segmenting hands and active objects in egocentric video. VISOR annotates videos from EPIC-KITCHENS, which comes with a new set of challenges not encountered in current video segmentation datasets. Specifically, we need…

COHESIV: Contrastive Object and Hand Embedding Segmentation In Video

NeurIPS 2021poster

In this paper we learn to segment hands and hand-held objects from motion. Our system takes a single RGB image and hand location as input to segment the hand and hand-held object. For learning, we generate responsibility maps that show how well a hand's motion explains other pixels' motion in video.…
