Correction of variable offsets relying upon scene

An image processing system comprising:

• a memory storing computer executable instructions;
• and
• image processor coupled to the memory, the computer executable instructions when executed by the image processor cause the image processor to:
• determine a suspicious pixel suspected of causing an artifact in a measurement as a function of a statistical analysis of a collection of samples representing residual error values associated with a subject focal plane pixel measuring one waveband at different times, given a residual cube derived from a data cube of measurements generated by a focal plane array, in which each sample of the residual cube is a residual error value in approximating the data cube as a linear combination of basis vectors;
• based on the determination of the suspicious pixel, identify a pattern of residual error values indicative of the artifact caused by the suspicious pixel;
• determine a correcting time-dependent offset substantially reciprocal to the identified pattern of residual error values;
• and
• apply the correcting time-dependent offset to the measurement to correct for the artifact in the measurement.

A non-transitory computer readable storage medium storing computer readable instructions for processing images, which when executed by one or more processors cause the one or more processors to:

• determine a suspicious pixel suspected of causing an artifact in a measurement as a function of a statistical analysis of a collection of samples representing residual error values associated with a subject focal plane pixel measuring one waveband at different times, given a residual cube derived from a data cube of measurements generated by a focal plane array, in which each sample of the residual cube is a residual error value in approximating the data cube as a linear combination of basis vectors;
• based on the determination of the suspicious pixel, identify a pattern of residual error values indicative of the artifact caused by the suspicious pixel;
• determine a correcting time-dependent offset substantially reciprocal to the identified pattern of residual error values;
• and
• apply the correcting time-dependent offset to the measurement to correct for the artifact in the measurement.
