Query: NuI-Go: Recursive Non-Local Encoder-Decoder Network for Retinal Image
  Non-Uniform Illumination Removal   Retinal images have been widely used by clinicians for early diagnosis of
ocular diseases. However, the quality of retinal images is often clinically
unsatisfactory due to eye lesions and imperfect imaging process. One of the
most challenging quality degradation issues in retinal images is non-uniform
which hinders the pathological information and further impairs the diagnosis of
ophthalmologists and computer-aided analysis.To address this issue, we propose
a non-uniform illumination removal network for retinal image, called NuI-Go,
which consists of three Recursive Non-local Encoder-Decoder Residual Blocks
(NEDRBs) for enhancing the degraded retinal images in a progressive manner.
Each NEDRB contains a feature encoder module that captures the hierarchical
feature representations, a non-local context module that models the context
information, and a feature decoder module that recovers the details and spatial
dimension. Additionally, the symmetric skip-connections between the encoder
module and the decoder module provide long-range information compensation and
reuse. Extensive experiments demonstrate that the proposed method can
effectively remove the non-uniform illumination on retinal images while well
preserving the image details and color. We further demonstrate the advantages
of the proposed method for improving the accuracy of retinal vessel
segmentation.
