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. date: 2024-01-01 date_type: published publisher: SPIE official_url: http://dx.doi.org/10.1117/12.3000082 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2274342 doi: 10.1117/12.3000082 isbn_13: 9781510670860 lyricists_name: Aksit, Kaan lyricists_id: KAKSI80 actors_name: Aksit, Kaan actors_id: KAKSI80 actors_role: owner full_text_status: public pres_type: paper publication: Proceedings of SPIE - The International Society for Optical Engineering volume: 12913 place_of_pub: San Francisco, CA, USA pagerange: 129130I event_title: Optical Architectures for Displays and Sensing in Augmented, Virtual, and Mixed Reality (AR, VR, MR) V event_dates: 29 Jan 2024 - 1 Feb 2024 issn: 0277-786X book_title: Proceedings of SPIE - The International Society for Optical Engineering editors_name: Hua, Hong editors_name: Argaman, Naamah editors_name: Nikolov, Daniel K citation: Zhan, Y; Kavakll, K; Urey, H; Sun, Q; Akşit, K; (2024) AutoColor: learned light power control for multi-color holograms.
