(a) Experiment setup for one-point deformation classification. (b) Average PCC for one-point deformation (the average PCC between the speckles collected in the first measurement and subsequently collected speckles in the rest 39 measurements). (c) Normalized confusion matrices for KNN classification results with one-point deformation experiment. KNN is trained by using only 50% dataset.
