Extremely Light-Weight Learning Based LDR to PQ HDR Conversion Using Bernstein Curves

The paper proposes a novel automatic Low Dynamic Range (LDR) to Perceptual Quantizer (PQ) High Dynamic Range (HDR) system to convert a LDR input into a HDR output. The process is based on a machine learning model that generates a Bernstein inverse tone mapping (iTM) curve. The monotonic constrain is…
