• Abstract summary: We propose a novel test-time optimization approach for efficiently tracking any pixel in a video. We introduce a novel invertible deformation network, CaDeX++, which factorizes the function representation into a local spatial-temporal feature grid. Our experiments demonstrate a substantial improvement in training speed (more than textbf10 times faster), robustness, and accuracy in tracking over the SoTA optimization-based method OmniMotion.

• Abstract: We propose a novel test-time optimization approach for efficiently and robustly tracking any pixel at any time in a video. The latest state-of-the-art optimization-based tracking technique, OmniMotion, requires a prohibitively long optimization time, rendering it impractical for downstream applications. OmniMotion is sensitive to the choice of random seeds, leading to unstable convergence. To improve efficiency and robustness, we introduce a novel invertible deformation network, CaDeX++, which factorizes the function representation into a local spatial-temporal feature grid and enhances the expressivity of the coupling blocks with non-linear functions. While CaDeX++ incorporates a stronger geometric bias within its architectural design, it also takes advantage of the inductive bias provided by the vision foundation models. Our system utilizes monocular depth estimation to represent scene geometry and enhances the objective by incorporating DINOv2 long-term semantics to regulate the optimization process. Our experiments demonstrate a substantial improvement in training speed (more than \textbf{10 times} faster), robustness, and accuracy in tracking over the SoTA optimization-based method OmniMotion.

  We propose a universal online temporal calibration strategy for optimization-based visual-inertial navigation systems. We use the time offset td as a state parameter in the optimization residual model to align the IMU state to the corresponding image timestamp. Our approach provides more accurate time offset estimation and faster convergence, particularly in the presence of noisy sensor data.

  OrientDream is a camera orientation conditioned framework for efficient and multi-view consistent 3D generation from textual prompts. Our strategy emphasizes the implementation of an explicit camera orientation conditioned feature in the pre-training of a 2D text-to-image diffusion module. Our experiments reveal that our method not only produces high-quality NeRF models with consistent multi-view properties but also achieves an optimization speed significantly greater than existing methods.
