“…From three-dimensional data acquisition techniques employing RGB and RGB-D sensors [1][2][3] to intricate processing procedures for holographic data, including three-dimensional (3D) object reconstruction [1,4,5], pose estimation [6,7], and activity prediction [8,9], the field is progressively evolving. In addition, the introduction of 5G [10][11][12][13], the anticipated emergence of 6G [14,15], and the application of AI technologies [16,17] will together enable the efficient transmission of voluminous data with minimal latency, potentially optimizing network performance and enhancing overall transmission efficacy. Lastly, rendering and AR/VR visualization have seen considerable advancements, with state-of-the-art methods like ray tracing [18,19] and neural radiance fields (NeRF) [20,21] offering increasingly realistic and immersive experiences.…”
