Query: Attention-Guided Progressive Neural Texture Fusion for High Dynamic
  Range Image Restoration   High Dynamic Range (HDR) imaging via multi-exposure fusion is an important
task for most modern imaging platforms. In spite of recent developments in both
hardware and algorithm innovations, challenges remain over content association
ambiguities caused by saturation, motion, and various artifacts introduced
during multi-exposure fusion such as ghosting, noise, and blur. In this work,
we propose an Attention-guided Progressive Neural Texture Fusion (APNT-Fusion)
HDR restoration model which aims to address these issues within one framework.
An efficient two-stream structure is proposed which separately focuses on
texture feature transfer over saturated regions and multi-exposure tonal and
texture feature fusion. A neural feature transfer mechanism is proposed which
establishes spatial correspondence between different exposures based on
multi-scale VGG features in the masked saturated HDR domain for discriminative
contextual clues over the ambiguous image areas. A progressive texture blending
module is designed to blend the encoded two-stream features in a multi-scale
and progressive manner. In addition, we introduce several novel attention
mechanisms, i.e., the motion attention module detects and suppresses the
content discrepancies among the reference images; the saturation attention
module facilitates differentiating the misalignment caused by saturation from
those caused by motion; and the scale attention module ensures texture blending
consistency between different coder/decoder scales. We carry out comprehensive
qualitative and quantitative evaluations and ablation studies, which validate
that these novel modules work coherently under the same framework and
outperform state-of-the-art methods.
