Laplacian cosmic-ray detection (L.A.Cosmic) in pure Julia.
To use the LACosmic library, first install it using
julia> ]add LACosmic
To import the library
there is one exported function:
clean_image, mask = lacosmic(image)
This code has been benchmarked against the Cython implementation in Astro-SCRAPPY. This benchmark simply computes the time it takes to run the LACosmic algorithm with different image sizes. The size is the length of one dimension of the image, so the expected scaling should be $\propto N^2$. The code can be found in
bench/benchmark.jl. Here is the information for my system-
