Augmentation Matters: A Simple-Yet-Effective Approach to Semi-Supervised Semantic Segmentation

CVPR 2023poster

Recent studies on semi-supervised semantic segmentation (SSS) have seen fast progress. Despite their promising performance, current state-of-the-art methods tend to increasingly complex designs at the cost of introducing more network components and additional training procedures. Differently, in thi…

Beyond Attentive Tokens: Incorporating Token Importance and Diversity for Efficient Vision Transformers

CVPR 2023poster

Vision transformers have achieved significant improvements on various vision tasks but their quadratic interactions between tokens significantly reduce computational efficiency. Many pruning methods have been proposed to remove redundant tokens for efficient vision transformers recently. However, ex…

HAP: Structure-Aware Masked Image Modeling for Human-Centric Perception

NeurIPS 2023poster

Model pre-training is essential in human-centric perception. In this paper, we first introduce masked image modeling (MIM) as a pre-training approach for this task. Upon revisiting the MIM training strategy, we reveal that human structure priors offer significant potential. Motivated by this insight…

Instance-Specific and Model-Adaptive Supervision for Semi-Supervised Semantic Segmentation

CVPR 2023poster

Recently, semi-supervised semantic segmentation has achieved promising performance with a small fraction of labeled data. However, most existing studies treat all unlabeled data equally and barely consider the differences and training difficulties among unlabeled instances. Differentiating unlabeled…

Task-Oriented Multi-Modal Mutual Leaning for Vision-Language Models

ICCV 2023poster

Prompt learning has become one of the most efficient paradigms for adapting large pre-trained vision-language models to downstream tasks. Current state-of-the-art methods, like CoOp and ProDA, tend to adopt soft prompts to learn an appropriate prompt for each specific task. Recent CoCoOp further boo…
