High-dynamic range compressive spectral imaging by grayscale coded aperture adaptive filtering
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2015-09-01)
The coded aperture snapshot spectral imaging system (CASSI) is an imaging architecture which senses the three dimensional informa-tion of a scene with two dimensional (2D) focal plane array (FPA) coded projection measurements. ...

Efficient reconstruction of raman spectroscopy imaging based on compressive sensing
(Universidad Nacional de Colombia Sede Medellín, 2014-12-15)
Raman Spectroscopy Imaging requires long periods of time for the data acquisition and subsequent treatment of the spectral chemical images. Recently, Compressed Sensing (CS) technique has been used satisfactorily in Raman ...

Modeling the closure behavior of natural fractures in porous media using high aspect ratio interface elements
(2021-01-01)
Many reservoirs consist of fully saturated rock masses containing a very complex natural fracture network. In such cases a decrease in the fracture fluid pressure reduces its aperture due to an increase in the effective ...
