a Algorithms for denoising. The figure illustrates the use of a random forest approach to differentiate real amplification signals from background noise after multimodal image fusion (figure adapted with permission from Kuhnemund et al. ¹⁰). b Algorithms for quantitative analysis. The figure illustrates the use of a random forest algorithm for colorimetric analysis and high-precision pH measurements (figure adapted with permission from Kim et al. ⁹⁶).
