4. As of this writing open source converterRawTherapeeprovides two implementations of RL deconvolution in its toolkit: as a method in the Detail/Sharpening tab – and as part of the Raw tab under the Capture Sharpening header. The latter is better and applied earlier in the pipeline on linear...
Richardson-Lucy deconvolution algorithm/ A9870R Cosmic gamma-ray sources A9575M Astronomical data and image processingThe Richardson–Lucy deconvolution algorithm was applied to astronomical images in the very high-energy regime with photon energies above 100GeV. Through a systematic study with respect ...
Lucy-Richardson algorithm. The algorithm maximizes the likelihood that the resulting image, when convolved with the PSF, is an instance of the blurred image, assuming Poisson noise statistics. This function can be effective when you know the PSF but know little about the additive noise in the im...
added one function in functional.py and one class in transforms.py file of RL (RichardsonLucy) deconvolution algorithm. the using test or example for it is given in functional.py file in documentation section. added richardson_lucy deconvolution algorithm to functional.py and tr… … 60fad69 ...
In our method, we perform two filtering steps with the Richardson-Lucy (RL) deconvolution. The advantage of this deconvolution algorithm over the Wiener filter is that it intrinsically accounts for the Poisson noise characteristic of the photon counting process in cameras. In our reconstruction ...

The number of times to iterate the deconvolution algorithm. flags The options to use when performing the operation. If your code implements its own tiling or its own multithreading, pass kvImageDoNotTile. Pass one of the following flags to specify how vImage handles pixel locations beyond the ...
I am trying to understand the Lucy-Richardson algorithm implementation in MATLAB, specifically if there is any thresholding being performed as a post-processing step?. I was able to implement a working algorithm, however, there were some contrast differences between my output and MATLAB o...
