Query: Deep SR-ITM: Joint Learning of Super-Resolution and Inverse Tone-Mapping
  for 4K UHD HDR Applications   Recent modern displays are now able to render high dynamic range (HDR), high
resolution (HR) videos of up to 8K UHD (Ultra High Definition). Consequently,
UHD HDR broadcasting and streaming have emerged as high quality premium
services. However, due to the lack of original UHD HDR video content,
appropriate conversion technologies are urgently needed to transform the legacy
low resolution (LR) standard dynamic range (SDR) videos into UHD HDR versions.
In this paper, we propose a joint super-resolution (SR) and inverse
tone-mapping (ITM) framework, called Deep SR-ITM, which learns the direct
mapping from LR SDR video to their HR HDR version. Joint SR and ITM is an
intricate task, where high frequency details must be restored for SR, jointly
with the local contrast, for ITM. Our network is able to restore fine details
by decomposing the input image and focusing on the separate base (low
frequency) and detail (high frequency) layers. Moreover, the proposed
modulation blocks apply location-variant operations to enhance local contrast.
The Deep SR-ITM shows good subjective quality with increased contrast and
details, outperforming the previous joint SR-ITM method.
