Linear Image Generation: RAW-Space Synthesis for Faithful Sensor Data
New method synthesizes linear (RAW) images by generating exposure brackets, bypassing traditional ISP pipelines that compress dynamic range and introduce artifacts. Critical for practitioners working with sensor-native data, computational imaging, and HDR pipelines where ISP stylization degrades downstream task performance.
