Giga-voxel multidimensional fluorescence imaging combining single-pixel detection and data fusion
Some time ago I wrote a short post about using Data Fusion (DF) to perform some kind of Compressive Sensing (CS). We came with that idea when tackling a common problem in multidimensional imaging systems: the more you want to measure, the harder it gets. It is not only the fact that you need a…

Single pixel hyperspectral bioluminescence tomography based on compressive sensing
Really cool implementation of Single-pixel Imaging + Compressive Sensing from the people at University of Birmingham. Using hyperspectral data measured with a single-pixel spectrometer + tomographic reconstruction, they show that it is possible to perform Bioluminiscence Imaging. Nice to see that the topics I used to work keep showing super cool results. Single pixel hyperspectral…

Data fusion as a way to perform compressive sensing
Some time ago I started working on some kind of data fusion problem where we have access to several imaging systems working in parallel, each one gathering a different multidimensional dataset with mixed spectral, temporal, and/or spatial resolutions. The idea is to perform 4D imaging at high spectral, temporal, and spatial resolutions using some single-pixel/multi-pixel…
