1. A computer program embodied on a computer-readable storage medium, the computer program configured to cause a processor to: extract reference pixel fast-varying components (IMFs) using Hilbert-Huang Transform Real-Time Data Processing (HHT1); derive a noise correction array based on a boundary condition equal to a first plurality of IMFs plus an absolute value of respective minimums of the IMFs, using an embedded squares method heat propagation model; and subtract the noise correction array from an active pixels array to yield active corrected pixels.
