    • A depth map post-processing approach based on adaptive random walk with restart 

      Javidnia, Hossein; Corcoran, Peter (Institute of Electrical and Electronics Engineers (IEEE), 2016-01-01)
      Accurate depth estimation is still an important challenge after a decade, particularly from stereo images. The accuracy comes from a good depth level and preserved structure. For this purpose, a depth post-processing ...
    • Application of preconditioned alternating direction method of multipliers in depth from focal stack 

      Javidnia, Hossein; Corcoran, Peter (Society of Photo-optical Instrumentation Engineers (SPIE), 2018-04-06)
      Postcapture refocusing effect in smartphone cameras is achievable using focal stacks. However, the accuracy of this effect is totally dependent on the combination of the depth layers in the stack. The accuracy of the ...
    • Contributions to the measurement of depth in consumer imaging 

      Javidnia, Hossein (NUI Galway, 2018-06-12)
      This thesis aims to examine and investigate methods that could potentially utilize images captured by consumer cameras such as smartphones to estimate depth and generate a 3D structure. After more than a century of ...
    • Semiparallel deep neural network hybrid architecture: first application on depth from monocular camera 

      Bazrafkan, Shabab; Javidnia, Hossein; Lemley, Joseph; Corcoran, Peter (Society of Photo-optical Instrumentation Engineers (SPIE), 2018-08-07)
      Deep neural networks have been applied to a wide range of problems in recent years. Convolutional neural network is applied to the problem of determining the depth from a single camera image (monocular depth). Eight different ...
    • Total variation-based dense depth from multicamera array 

      Javidnia, Hossein; Corcoran, Peter (Society of Photo-optical Instrumentation Engineers (SPIE), 2018-05-20)
      Multicamera arrays are increasingly employed in both consumer and industrial applications, and various passive techniques are documented to estimate depth from such camera arrays. Current depth estimation methods provide ...
