Spectrum Preservation in Failed Hyperspectral Detector Correction

A non-transitory machine-readable medium including instructions that, when executed by a machine, cause the machine to perform operations for improving failed detector correction (FDC), the operations comprising:

• determining first pixel data of a first frequency band of frequency bands of a pixel of a hyperspectral image corresponds to a failed detector;
• determining a neighboring pixel of neighboring pixels of the pixel that has a corresponding first spectral profile (i) most similar to a second spectral profile of the pixel and (ii) corresponds to a non-failed detector;
• determining second pixel data from the first spectral profile;
• and
• replacing the first pixel data with second pixel data in the second spectral profile.
