ABO: Abandon Bayer Filter for Adaptive Edge Offloading in Responsive Augmented Reality
Yongxuan Han, Shengzhong Liu, Fan Wu, Guihai Chen · 2025
Bayer-patterned color filter array (CFA) has been the go-to solution for color image sensors. In augmented reality (AR), although color interpolation (i.e., demosaicing) of pre-demosaic RAW images facilitates a user-friendly rendering, it creates no benefits in offloaded DNN analytics but increases the image channels by 3x inducing higher transmission overheads. The potential optimization in frame preprocessing of DNN offloading is yet to be investigated.
