Fiscal impacts and cross-border effects of a change in state liquor policy
(2020-07)
This paper analyzes the economic effects of the 2012 change in liquor policy (Initiative 1183) in Washington State in the United States. This policy increased the availability of liquor but also increased taxes on liquor ...
Wide-field 3D imaging with an LED pattern projector for accurate skin feature measurements via Fourier transform profilometry
(SPIE, 2019)
Accurate 3D imaging of human skin features with structured light methods is hindered by subsurface scattering, the presence of hairs and patient movement. In this work, we propose a wide-field 3D imaging system capable of ...
