Definition:
Deconvolution is a mathematical process used to reverse the effects of convolution on a signal. In the context of signal processing, convolution is a mathematical operation that combines two signals to produce a third signal. Deconvolution, therefore, aims to separate the original signals from the combined signal. This process is widely used in various fields such as image processing, seismic data analysis, and microscopy to enhance the resolution and clarity of the original signals.
Deconvolution involves the application of algorithms and techniques to remove or reduce the blurring and distortion caused by the convolution process. It is a fundamental tool in signal and image processing, enabling the extraction of valuable information from complex and distorted data.
