LENS: Learning to Segment Anything with Unified Reinforced Reasoning

AAAI 2026technical

Text-prompted image segmentation enables fine-grained visual understanding and is critical for applications such as human-computer interaction and robotics. However, existing supervised fine-tuning methods typically ignore explicit chain-of-thought (CoT) reasoning at test time, which limits their ab

TransLight: Image-Guided Customized Lighting Control with Generative Decoupling

ICML 2026poster

Most existing illumination-editing methods struggle to jointly offer customized lighting control and preserve content integrity, limiting their effectiveness especially in transferring complex light effects from a reference to a target image in portrait photography. To address this problem, we propo…

ControlAR: Controllable Image Generation with Autoregressive Models

ICLR 2025poster

Autoregressive (AR) models have reformulated image generation as next-token prediction, demonstrating remarkable potential and emerging as strong competitors to diffusion models. However, control-to-image generation, akin to ControlNet, remains largely unexplored within AR models. Although a natural…

GroundingSuite: Measuring Complex Multi-Granular Pixel Grounding

ICCV 2025poster

Pixel grounding, encompassing tasks such as Referring Expression Segmentation (RES), has garnered considerable attention due to its potential for bridging the gap between vision and language modalities. However, advancements in this domain are currently constrained by limitations inherent in existin…

Weakly-Supervised Instance Segmentation via Class-Agnostic Learning With Salient Images

CVPR 2021poster

Humans have a strong class-agnostic object segmentation ability and can outline boundaries of unknown objects precisely, which motivates us to propose a box-supervised class-agnostic object segmentation (BoxCaseg) based solution for weakly-supervised instance segmentation. The BoxCaseg model is join…
