From: Sparse point spread function-based multi-image optical encryption

Fig. 6

a The process of eliminating the effect of ambient light with PCA; b Illustration of PCA; c Comparison of reconstructed results w/o PCA. Bg background, P-PCA, processed by principal component analysis, Rec without PCA the reconstructed image obtained without applying principal component analysis, Rec with PCA the reconstructed image obtained after applying principal component analysis.
