Some embodiments of the present invention pertain to an apparatus, method, and a computer program that is configured to cause a processor to construct an upper envelope and lower envelope for an input image based on a statistically computed window parameter in a real-time system using multi-thread processing, and smooth the upper envelope and lower envelope based on a sum of elements in a window, wherein the sum of elements in the window is divided by a number of non-zero elements in the sum of elements in the window.

Hilbert-huang transform data processing real-time system with 2-D capabilities

An improved method for correcting for noise in the digital domain is disclosed. Reference pixel fast-varying components are extracted using a Hilbert-Huang Transform Real-Time Data Processing System (HHT-DPS-RT). The reference pixels are non-photon-detecting pixels in a sensor array. The fast-varying components of the reference pixels are processed in addition to the average over the remaining trend, facilitating additional noise correction for active pixels.
