Fig. 5: Real-time experiment and application on the microscope: Analysis for PTO sample 2: BOARS with local image patches and utilizing dKL.

a–f GP estimated structural similarity map (left) and respective uncertainty map (right) for stated BO iterations. In the figures, the green dots are the explored locations while the red dots are the new locations to be explored on the next iteration. g analysis after BO convergence with 100 iterations. (left) high-resolution (128 × 128) PFM amplitude image of the PTO film, with all the explored spectral locations till BO convergence, (middle) GP prediction of structural similarity, and (right) associated uncertainty map. Scale bar in g is 200 nm. The sample color coding represents (red being higher values and blue being lower values) the color of the explored locations with the objective function values (100 BO iterations) in (g).
