Mobile Mapping System Calibration Spherical Photogrammetry
2016/7/5
A spherical camera can observe the environment for almost 720 degrees’ field of view in one shoot, which is useful for augmented reality, environment documentation, or mobile mapping applications. Thi...
Faster sieving for shortest lattice vectors using spherical locality-sensitive hashing
shortest vector problem (SVP), sieving algorithms, nearest neighbor problem
2016/1/3
Recently, it was shown that angular locality-sensitive hashing (LSH) can be used to significantly speed up lattice sieving, leading to a heuristic time complexity for solving the shortest vector probl...
