Abstract:
A system for converting image data from standard dynamic range (SDR) format to a high dynamic range (HDR) format involves partitioning input data representing a SDR image into a plurality of portions of data, wherein each portion represents a respective one of a plurality of SDR patches of the SDR image and each of the plurality of SDR patches covers a portion of the SDR image and the set of the plurality of SDR patches fully covers the SDR image; processing each of the plurality of SDR patches through a deep learning autoencoder responsive to a plurality of model weights representing a model of SDR to HDR conversion to produce a respective plurality of estimated HDR patches; and stitching the estimated HDR patches together to form a HDR image version of the SDR image.
