AutoColor: Learned Light Power Control for Multi-Color Holograms
This addresses the efficiency challenge in holographic displays for applications like AR/VR, though it is incremental as it builds on existing hologram optimization methods.
The paper tackled the problem of optimizing light source powers for multi-color holograms by introducing AutoColor, a learned method that reduced the required iteration steps from over 1000 to 70 while maintaining image quality.
Multi-color holograms rely on simultaneous illumination from multiple light sources. These multi-color holograms could utilize light sources better than conventional single-color holograms and can improve the dynamic range of holographic displays. In this letter, we introduce AutoColor , the first learned method for estimating the optimal light source powers required for illuminating multi-color holograms. For this purpose, we establish the first multi-color hologram dataset using synthetic images and their depth information. We generate these synthetic images using a trending pipeline combining generative, large language, and monocular depth estimation models. Finally, we train our learned model using our dataset and experimentally demonstrate that AutoColor significantly decreases the number of steps required to optimize multi-color holograms from > 1000 to 70 iteration steps without compromising image quality.
