  • After applying the deconvolution algorithm, the blurred image became much clearer.

And they have to do what's called deconvolution where they extract out the victim's DNA and are left with just that suspect's DNA.

Examples

  • The image has a full-width, half-maximum resolution of 0.15 arcsec after deconvolution, which further enhances its quality.

  • The deconvolution of the broadened a-C:H spectra resembles the microcrystalline graphite spectra.

  • Unfortunately, the deconvolution transformation does not preserve the statistical distance between two distributions.

    Academic text (2012)

  • The deconvolution operation gives us a method to produce a large statistical distance between two mixtures with sufficiently different parameters.

    Academic text (2012)

  • Deconvolution imaging makes it possible to overcome the limits of numeric aperture to produce images with resolution or depth of field that exceed what is possible with a single image (Angel and Fugate 2000).

    Academic text (2010)

  • The deconvolution process helped restore the original quality of the distorted signal.

  • Using deconvolution, the scientists were able to improve the resolution of the captured images.

Morphology

deconvolution = convolution (semi-transparent) = de + convolution

The prefix 'de-' productively indicates reversal/removal when attached to a process noun, so the formation from 'convolution' to 'deconvolution' is morphologically regular.

Etymology

The word deconvolution breaks into de- meaning 'remove' and convolution meaning 'to roll together', which is the same root you see in revolve. So deconvolution is a way of 'unrolling' mixed or blurred data to remove distortion and bring back the original image or sound.
