Depth-Conditioned GAN for Underwater Image Enhancement
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.

Depth-of-Field Enhancement in Integral Imaging by Selective Depth-Deconvolution [PDF]
One of the major drawbacks of the integral imaging technique is its limited depth of field. Such limitation is imposed by the numerical aperture of the microlenses. In this paper, we propose a method to extend the depth of field of integral imaging systems in the reconstruction stage.

Image enhancement by unsharp masking the depth buffer [PDF]
We present a simple and efficient method to enhance the perceptual quality of images that contain depth information. Similar to an unsharp mask, the difference between the original depth buffer content and a low-pass filtered copy is utilized to determine information about spatially important areas in a scene.

Edge enhancement of depth based rendered images [PDF]
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 ...
