PDSeg: Patch-Wise Distillation and Controllable Image Generation for Weakly-Supervised Histopathology Tissue Segmentation

ICASSP 2025accepted

Weakly-supervised semantic segmentation, which achieves pixel-wise segmentation using image-level labels, has emerged as an alternative to fully supervised methods by reducing the need for detailed annotations. Inspired by the recent success of the teacher-student strategy in various vision tasks, w…

Relation-Rich Visual Document Generator for Visual Information Extraction

CVPR 2025poster

Despite advances in Large Language Models (LLMs) and Multimodal LLMs (MLLMs) for visual document understanding (VDU), visual information extraction (VIE) from relation-rich documents remains challenging due to the layout diversity and limited training data. While existing synthetic document generato…

ACCEPT: Adaptive Codebook for Composite and Efficient Prompt Tuning

EMNLP 2024finding

Prompt Tuning has been a popular Parameter-Efficient Fine-Tuning method attributed to its remarkable performance with few updated parameters on various large-scale pretrained Language Models (PLMs). Traditionally, each prompt has been considered indivisible and updated independently, leading the par…

SAM4MLLM: Enhance Multi-Modal Large Language Model for Referring Expression Segmentation

ECCV 2024poster

"We introduce SAM4MLLM, an innovative approach which integrates the Segment Anything Model (SAM) with Multi-Modal Large Language Models (MLLMs) for pixel-aware tasks. Our method enables MLLMs to learn pixel-level location information without requiring excessive modifications to the existing model ar…
