Definition of deconvolution in US English:



  • 1A process of resolving something into its constituent elements or removing complication in order to clarify it.

    1. 1.1Mathematics The resolution of a convolution function into the functions from which it was formed in order to separate their effects.
      • ‘Mathematical procedures, such as Fourier deconvolution and derivation, have been developed to circumvent this problem.’
      • ‘In general, deconvolution decreases the exponential formation time by 0.07 + or - 0.02 ps.’
      • ‘The deconvolution was made in a wavenumber function and then transferred to the wavelength function for representation in the figures.’
      • ‘In those experiments Fourier deconvolution was used to calculate the spatial function, but that approach is not applicable for a sample containing multiple radical species.’
      • ‘Fourier transformation deconvolution is only applicable to samples composed of a single radical species.’
    2. 1.2 The improvement of resolution of images or other data by a mathematical algorithm designed to separate the information from artifacts which result from the method of collecting it.
      • ‘He reported that deconvolution of the high-resolution images was going well, and showed a pretty red-green-blue image with a noticeably brown tinge to it.’
      • ‘The resolution of this image was computationally enhanced by deconvolution.’
      • ‘After deconvolution, 3D-reconstruction algorithms are applied.’
      • ‘The raw data in and after imaging was subjected to linear deconvolution to mathematically slightly enhance the resolution.’
      • ‘The out-of-focus fluorescence in 3 - D images recorded by WFFM can be computationally removed using deconvolution.’
