Summary
[edit]DescriptionRichardson-Lucy deconvolution gone wild simplified.gif |
English: A demonstration of the Richardson–Lucy deconvolution algorithm to some synthetic one-dimensional data.
The top plot shows the original unknown signal (sometimes called the source). The middle plot shows the measured degraded signal (sometimes called the image), which is the original signal convolved with an impulse-response function and degraded with Poisson noise, as is realistic for many forms of measurement. The bottom plot shows the signal inferred by applying some number of Richardson–Lucy iterations to the measurement. The plot stops after 11000 iterations, which is sufficient for Richardson–lucy to overfit the noisy data considerably. For a shorter animation that stops when the fit is still reasonable, see File:Richardson-Lucy deconvolution simplified.gif.
