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.

Depth-of-Field Enhancement in Integral Imaging by Selective Depth-Deconvolution [PDF]
Journal of Display Technology, 2014 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]
ACM SIGGRAPH 2006 Papers on - SIGGRAPH '06, 2006 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.
