Planning and Rendering in Concert: DeepFusion of Autoregressive Layouts and Diffusion for Visual Text Generation

Generating text-rich images from prompts requires both textual fidelity and the coherent integration of text into the surrounding image. An explicit layout can provide structured guidance about what text should appear and where, but a well-formed plan alone does not guarantee that the renderer will realize it faithfull...

Efficient Frame Selection for Long Videos at Test Time with Attention-Based MLLM Selectors

DAFS (Dynamic Attention-based Budget-aware Frame Selection), a training-free frame selector that improves over uniform sampling by up to 6.4 points on Video-MME and outperforms prior training-based selectors under matched frame budgets, while generalizing across selector and answerer backbones, and across tasks, withou...

Same Semantics, Different Paths: Self-Improving Alignment for Vision-Text Compression

SPIRAL (Self-improving Path Integration and Realignment), a self-supervised alignment framework that closes this gap using only the model's own text-path behavior as supervision, requiring no external teachers or additional annotations, generalize to out-of-domain benchmarks, confirming that effective VTC hinges on ali...
