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.

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 ...

A method for measuring the contact area in instrumented indentation testing by tip scanning probe microscopy imaging [PDF]
, 2014 The determination of the contact area is a key step to derive mechanical properties such as hardness or an elastic modulus by instrumented indentation testing. Two families of procedures are dedicated to extracting this area: on the one hand, post mortem

Single-breath-hold photoacoustic computed tomography of the breast [PDF]
, 2018 We have developed a single-breath-hold photoacoustic computed tomography (SBH-PACT) system to reveal detailed angiographic structures in human breasts. SBH-PACT features a deep penetration depth (4 cm in vivo) with high spatial and temporal resolutions ...

Deep learning-based single image face depth data enhancement
Computer Vision and Image Understanding, 2021 Face recognition can benefit from the utilization of depth data captured using low-cost cameras, in particular for presentation attack detection purposes. Depth video output from these capture devices can however contain defects such as holes or general depth inaccuracies. This work proposes a deep learning face depth enhancement method in this context
