摘要

Various embodiments relate to an apparatus, method and a non-transitory computer readable medium for fringe detection and mitigation in an image using Hilbert-Huang Transform (“HHT2-Fringe”) configured to apply Empirical Mode Decomposition (“EMD2”) to a measured light intensity suppression to generate bi-dimensional intrinsic mode functions (“BIMFs”), apply Hilbert Spectral Analysis (“HSA2”) to analyze a plurality of outer fringe bright bands of the BIMFs, propagating the amplitudes of the plurality of outer fringe bright bands of the BIMFs into the center of the image using linear approximation, determine fringe magnitudes of the BIMFs, adding the magnitudes of the BIMFs and subtracting the difference from magnitudes of a petal area of the image.
