The use of Richardson–Lucy deconvolution to recover a signal blurred by an impulse response function. The Richardson–Lucy algorithm, also known as Lucy–Richardson deconvolution, is an iterative procedure for recovering an underlying image that has been blurred by a known point spread function.
Before and after deconvolution of an image of the lunar crater Copernicus using the Richardson-Lucy algorithm. In mathematics, deconvolution is the inverse of convolution. Both operations are used in signal processing and image processing. For example, it may be possible to recover the original signal after a filter (convolution) by using a ...
Leon B. Lucy (1938–2018) was a British-American astrophysicist, best known for his contribution to the Richardson-Lucy deconvolution algorithm and spearheading the development of smoothed-particle hydrodynamics methods. [1] He won the Gold Medal of the Royal Astronomical Society in 2000.
The Lucy-Richardson-Rosen algorithm was initially demonstrated to deconvolve blurred mid infrared images obtained from the microspectroscopy system of Australian synchrotron. Later, it was found to exhibit good deconvolution for spatially symmetric point spread functions .
The mean response was obtained by averaging all line scans, the variance response was obtained by applying the square root of the signal variance at each spatial position, the Richardson-Lucy deconvolution (RLD) response was obtained by performing the deconvolution of the mean response with the given Gaussian PSF, and the BSIPAM response was ...
President Donald Trump said he is in favor of Elon Musk or Larry Ellison buying TikTok as he offered his latest thinking on what a deal might look like to save the US operations of the social ...
Soft drinks with added sugar might increase a person's risk of type 2 diabetes by affecting their gut microbiome, new research suggests.
The algorithm estimates the PSF by comparing the spatial frequency information in the blurred image to that of the target image. Examples. Any blurred image can be given as input to blind deconvolution algorithm, it can deblur the image, but essential condition for working of this algorithm must not be violated as discussed above.
