The recent developments in the field of dynamic scene representation and neural rendering have been significantly influenced by advancements in 3D Gaussian Splatting (3DGS) techniques. These advancements aim to address the challenges of memory efficiency, temporal consistency, and the representation of complex real-world motions. Innovations include the introduction of frameworks that decompose motion from global to local scales, enabling more efficient and accurate dynamic scene reconstructions. Additionally, there has been a notable shift towards leveraging synthetic datasets and environments to facilitate the adaptation of object detection models to new domains, thereby reducing the reliance on costly real-world data acquisition and labeling. Another key trend is the development of frameworks that bridge the sim-to-real gap, enabling the creation of photorealistic and physically interactable 3D simulation environments from monocular videos. These environments are crucial for training visual navigation agents in complex urban settings. Furthermore, the exploration of implicit neural representations (INRs) for video modeling has led to the development of frameworks capable of achieving high-quality video processing tasks, such as slow motion, super resolution, denoising, and inpainting, with remarkable efficiency and performance.
