A wide range of approaches have been developed for camera pose estimation, including correspondence-based methods, end-to-end pose regression, and recent 3D geometric foundation models. Our key observation is that no single estimator is optimal for diverse challenges, such as wide baselines, lack of texture, appearance...

Video generation models have demonstrated emerging zero-shot capabilities for visual reasoning, perception, and other vision tasks. However, diffusion-based video generation is inherently stochastic, while many downstream vision tasks are deterministic. Motivated by the effectiveness of self-consistency in chain-of-tho...
This training-free method improves the performance of both U-Net-based and Transformer-based diffusion models, including the Stable Diffusion series and FLUX series and adapts self-cross guidance as an effective reward for RL-based post-training and show improved subject diversity with no computational overhead at infe...
