Four lenses and a Spatial Light Modulator allow each pixel to have a different focal length in research from Carnegie Mellon ...
Abstract: 2D-3D point or line correspondences are usually used to estimate the camera pose and intrinsic parameters, such as the focal length. There are many point-based methods and line-based methods ...
Abstract: The focal mechanism provides seismological constraints on the geological faults that generate the earthquakes and thus is important for regional seismotectonic research. Focal mechanism ...
