BrainOOD: Out-of-distribution Generalizable Brain Network Analysis

ICLR 2025poster

In neuroscience, identifying distinct patterns linked to neurological disorders, such as Alzheimer's and Autism, is critical for early diagnosis and effective intervention. Graph Neural Networks (GNNs) have shown promising in analyzing brain networks, but there are two major challenges in using GNNs…

Text4Seg: Reimagining Image Segmentation as Text Generation

ICLR 2025poster

Multimodal Large Language Models (MLLMs) have shown exceptional capabilities in vision-language tasks; however, effectively integrating image segmentation into these models remains a significant challenge. In this paper, we introduce Text4Seg, a novel text-as-mask paradigm that casts image segmentat…

ClearCLIP: Decomposing CLIP Representations for Dense Vision-Language Inference

ECCV 2024poster

"Despite the success of large-scale pretrained Vision-Language Models (VLMs) especially CLIP in various open-vocabulary tasks, their application to semantic segmentation remains challenging, producing noisy segmentation maps with mis-segmented regions. In this paper, we carefully re-investigate the…

ProxyCLIP: Proxy Attention Improves CLIP for Open-Vocabulary Segmentation

ECCV 2024poster

"Open-vocabulary semantic segmentation requires models to effectively integrate visual representations with open-vocabulary semantic labels. While Contrastive Language-Image Pre-training (CLIP) models shine in recognizing visual concepts from text, they often struggle with segment coherence due to t…

MIMO Is All You Need:A Strong Multi-in-Multi-Out Baseline for Video Prediction

AAAI 2023technical

The mainstream of the existing approaches for video prediction builds up their models based on a Single-In-Single-Out (SISO) architecture, which takes the current frame as input to predict the next frame in a recursive manner. This way often leads to severe performance degradation when they try to e…

SmooSeg: Smoothness Prior for Unsupervised Semantic Segmentation

NeurIPS 2023poster

Unsupervised semantic segmentation is a challenging task that segments images into semantic groups without manual annotation. Prior works have primarily focused on leveraging prior knowledge of semantic consistency or priori concepts from self-supervised learning methods, which often overlook the co…
