deconvolution

Deconvolution is a mathematical process used to reverse or undo the effects of a system that blurs or distorts a signal, such as an image or audio. Imagine taking a clear picture that gets blurred due to camera movement; deconvolution helps reconstruct the original sharp image by analyzing how the blur occurred. It relies on understanding the system's response (how it distorts signals) to restore the original signal more accurately. This technique is common in fields like astronomy, medical imaging, and signal processing, enhancing clarity and detail from imperfect data.
