Depth-Conditioned GAN for Underwater Image Enhancement
IEEE Access, 2023 Autonomous underwater vehicles perceive environmental information relying on vision. However, the variety of the underwater environment always leads to image distortion. To effectively obtain color-corrected images that guarantee high sharpness and good content recovery, this paper proposes an algorithm based on deep learning networks.

Spatial and Angular Resolution Enhancement of Light Fields Using Convolutional Neural Networks [PDF]
, 2018 Light field imaging extends the traditional photography by capturing both spatial and angular distribution of light, which enables new capabilities, including post-capture refocusing, post-capture aperture control, and depth estimation from a single shot.

Edge enhancement of depth based rendered images [PDF]
2014 IEEE International Conference on Image Processing (ICIP), 2014 Depth image based rendering is a well-known technology for the generation of virtual views in between a limited set of views acquired by a cameras array. Intermediate views are rendered by warping image pixels based on their depth. Nonetheless, depth maps are usually imperfect as they need to be estimated through stereo matching algorithms; moreover ...

In vivo analysis of glaucoma-related features within the optic nerve head using enhanced depth imaging optical coherence tomography. [PDF]
PLoS One, 2017 Structural differences between optic nerve head (ONH) parameters in glaucomatous and non-glaucomatous eyes has been documented, however the association between such parameters in patients with different disease stages is yet to be elucidated.

Investigative Ophthalmology and Visual Science, 2017 Purpose Optic disc drusen (ODD) are found in up to 2.4% of the population and are known to cause visual field defects. The purpose of the current study was to investigate how quantitatively estimated volume and anatomic location of ODD influence optic ...
