👉 Redintegration is a mathematical technique used in signal processing and image analysis. It involves filtering an input signal to reduce noise while preserving important features of the original signal. Redintegration can be thought of as a type of low-pass filter, but it is more specifically applied to the case where the input signal is a function of time instead of frequency. Redintegration works by selecting high-frequency components (often called "red" or "highpass") and removing low-frequency components (often called "lowpass").
