Optimal multispectral illumination patterns determined by the learned sensing network for thick-smear malaria classification. Network optimization is jointly performed over 3 LED colors and 40 locations simultaneously. Dashed line denotes bright-field/dark-field cutoff. Optimized pattern uses a similar phase contrast mechanism as with the thin smear, but converges towards a distinctly unique spatial pattern and multispectral profile.
